In Excel I can add the following formula...
=IF(A1="", "", IF(B1="", NOW(), B1))
This formula says when a value in added to cell A1 populate cell B1 with the current date. To get this to work you must turn on an Excel feature named iterative calculation (Options==>Formulas==>Enable iterative calculation).
I use this when I'm building an Excel task journal and I want to auto-populate the date.
The important thing about this formula is that the date value is not updated if another change is made.
In Numbers, how can I auto populate a date value in column "B" when a value is set in column "A"? It's important to keep in mind that once the date is set I don't want it to change.
Here is my attempt at translating this formula in Apple Numbers.
=IF(A2="", "", IF(B2="", NOW(), B2))
I get an error message.
This formula can't reference its own cell, or depend on another formula that references this cell

I am trying to write a formula in a Range of cells based on other range cells values from another worksheet. The formula is shown below:
ActiveSheet.Range("G14:G43").Formula = "=Worksheets("1ºperíodo").Range("V14:V43").Value"
But the code doesn't work and I get a syntax error. That must be related with the strings but I don't know how to fix it.
The value at V14 must be equal to the value at G14 until the last cell, i.e., the value at G14 equals the value at V43. Besides the syntax error is the formula correct based on what I expect to have?
"=Worksheets("1ºperíodo").Range("V14:V43").Value"
is not a formula. It is a value.
If you only want the static values then just assign the values:
ActiveSheet.Range("G14:G43").Value = Worksheets("1ºperíodo").Range("V14:V43").Value
If you want a live formula you need to pull vba from the string and use the .Address function:
ActiveSheet.Range("G14:G43").Formula = "=" & Worksheets("1ºperíodo").Range("V14").Address(0,0,,1)
But the above can be simplified to:
ActiveSheet.Range("G14:G43").Formula = "='1ºperíodo'!V14"
With the formula, we only need to refer to the first cell with a relative reference and vba will make the changes to each row.
Ive a sheet in which a cell value to be dynamically changed based on the cell value in the same row. So we have to pick that cell value first and then use that value to search in another sheet. Here is the code I have got. The sheet I have to search is Mapper
ActiveSheet.Range("P2").Select
formularwcount = ActiveSheet.UsedRange.Rows.Count
ActiveCell.FormulaR1C1 = "=VLOOKUP(RC[-11], Mapper!C[-13]:C[2],3,FALSE)"
In this code they are using R1C1 convention which I didnt understand what they mean by putting Mapper!C[-13]:C[2] there as the table array. Im only a 10 days old developer with VBA. Anyone please tell what does that mean.
I found this information by Googling "R1C1":
Cell References
In place of a named cell, an alternative approach is to use a cell (or grid) reference. Most cell references indicate another cell in the same spreadsheet, but a cell reference can also refer to a cell in a different sheet within the same spreadsheet, or (depending on the implementation) to a cell in another spreadsheet entirely, or to a value from a remote application.
A typical cell reference in "A1" style consists of one or two case-insensitive letters to identify the column (if there are up to 256 columns: A–Z and AA–IV) followed by a row number (e.g., in the range 1–65536). Either part can be relative (it changes when the formula it is in is moved or copied), or absolute (indicated with $ in front of the part concerned of the cell reference).
The alternative "R1C1" reference style consists of the letter R, the row number, the letter C, and the column number; relative row or column numbers are indicated by enclosing the number in square brackets. Most current spreadsheets use the A1 style, some providing the R1C1 style as a compatibility option.

I am having an issue with a cell that has a formula in it, but it's not calculating. I am using Excel 2013 and the data is as follows:
I have 12 cells(z14:ab17) the user will place a numeric value in. The formulated cell has a formula that uses the numeric cells to calculate a value, but all the cell displays is #VALUE!. The formula is
=IF((ISNUMBER(SUM(Z14:AB17))),PI()/4/32^2*(Z14^2+AA14^2+AB14^2+Z15^2+AA15^2+AB15^2+Z16^2+AA16^2+AB16^2+Z17^2+AA17^2+AB17^2),0).
In the VBA side, I have
Global Const PI = 3.1415927
All the user input cells are formatted for numeric values, and the formulated cell is also formulated to calculate and display a numeric value. Can anyone help with why the cells is not calculating? This did work at one time, but now it doesn't and I have no idea what could have happened. Thanks in advance
I have a table that uses a bit of vba to populate column b with id numbers.
I then have column c as a vlookup that gets a name based off the id, from another sheet. The vlookup in the first cell works fine and returns the correct name, John Doe.
When I drag down, the rest of the cells in column c return the same name as the first, John Doe. The vlookup in the other cells is exactly the same, except the reference cell does change, as expected....so, c2 = vlookup(b2, $range, col, false), c3= vlookup(b3..), c4=vlookup(b4,..), etc.
The catch is, when I look at the vlookup in c3 and click on b3, the cell changes to find the correct name (no longer John Doe). So it works fine. And I have to do that for every cell in column c.
It's like vlookup isn't aware that column b changed? Is that something that happens with vba? Is there a refresh command or some other way for vlookup to register that column b has changed without having to click on each individual vlookup function?
If you've entered a formula in a cell, then copied the formula to another cell and Excel hasn't updated your results, that means that Calculation Mode is Manual.
To fix it (depending on version, this is for Excel 2010)
Click on Formulas in the Ribbon
Click on Calculation Options
Click on Automatic
If you need to have it calculate manually (valuable for making many formula changes in a large worksheet):
Click on Formulas in the Ribbon
Click on Calculate Now to calculate the entire workbook, or
Click on Calculate Sheet to calculate the current worksheet
You can skip all the clicking by pressing F9 to Calculate Now or Shift-F9 to Calculate Sheet.
This is my first time using this forum, and my VBA skill is not very well developed. I hope someone can help.
I have two columns of data, Column A and Column B.
Column A - Returns a sequential "month-year" or 0. If spreadsheet current date (=now()) is less than say Feb, then the cell for February returns 0.
Column B - I want this column to check each cell in Column A. If Column A cell has a date identifier, I want this to be placed in Column B. If Column A has a 0 identifier, I want Column B to return an "empty" cell.
Reason why I am doing this is I am graphing a bar chart. When I trick the program into making an empty cell (x-axis) the graph does not show any data for that month (which is what I want). Trying to make a dynamic graph, but I have no experience in VBA (only C programming =/).
You don't need VBA (or even formulas) to do this.
Highlight Column A (the entire column), copy it.
Highlight Column B (the entire column, right click, Paste Special, select values and number formats, okay.
Highlight Column B again. Press Ctrl+H, Type 0 (or failing that it might be 00/01/1900) in the 'find what', leave the 'replace with' one blank. Tick Match entire cell contents. Click replace all.
Done.
Instead of trying for an empty space (which would be impossible, as there's a formula in that cell), use an error condition.
Use this formula, and copy down:
=IF(A1=0,NA(),A1)
This will return the error condition #NA! and Excel will leave the column blank
The other way would be to have a dynamic range for the chart data - I have a chart that will adjust to 5,6 or 7 days, depending on the data returned for the week. The Horizontal (Category) Axis Labels is set to a named range (='Sample.xlsx'!LastWeekRange) and the range checks the data, and returns the appropriate number of cells.
LastWeekRange is defined in Name Manager as =OFFSET(Data!$A$3,0,0,IF(Data!$F$9>0,7,IF(Data!$F$8>0,6,5))), which returns A3:A7 if there's nothing in F8, A3:A8 if there is something in F8 but not in F9, and A3:A9 if there is something in F9.
