Excel VBA Range(Cell).Value=sum 1004:Application-Defined Or Object-Defined - vba

Question

Function ChangeColVal(ByVal Rng As Range, ByVal ValueToChange As Integer)
Dim Cell1, Cell2 As String
Dim PosOfColon, TotalCell, Sum As Integer
PosOfColon = InStr(1, Rng.Address, ":")
Cell1 = Left(Rng.Address, PosOfColon - 1)
Cell2 = Right(Rng.Address, Len(Rng.Address) - PosOfColon)
If Left(Cell1, 2) = Left(Cell2, 2) Then
TotalCell = Rng.Count
For i = 0 To TotalCell
If IsNumeric(Range(Cell1).Offset(i, 0).Value) = False Then
GoTo 112:
End If
Cell2 = Range(Cell1).Offset(i, 0).Address
Sum = Range(Cell2).Cells.Value + ValueToChange
On Error GoTo 111
'Here getting error...
Range(Cell2).Value = Sum
GoTo 112
111:
MsgBox (Err.Number & ":" & Err.Description)
112:
Next i
Else
MsgBox ("Select Column only...")
End If
End Function
I wants to increase or decrease cell value of selected range.
I am getting error in line Range(Cell2).Value = Sum
Edit
thanx for reply, in line Range(Cell2).Value = Sum, Cell2 is pointing to cell address like $E$6.
If there is any option other than that pls let me know

Answer 1

ok Mihir. You cannot use a UDF (User Defined Function) to modify other cells then the one the formula is used in. However, there is a workaround it by calling your function from a sub. I will show you how to do it.
Open a new workbook and make your spreadsheet look like the picture below.
Fill in some random numbers in column A of Sheet1
Then open VBE and create a new module ( Project Explorer > Insert > Module ) and paste the code from below
Option Explicit
Sub ChangeColumnValue()
Dim rng As Range
Set rng = Selection
Dim inp As String
inp = InputBox("Value to change:")
Call ChangeColVal(rng, CLng(inp))
End Sub
Private Function ChangeColVal(ByRef rng As Range, ByVal ValueToChange As Long)
Dim Cell1, Cell2 As String
Dim PosOfColon, TotalCell, Sum As Long
PosOfColon = InStr(1, rng.Address, ":")
Cell1 = Left(rng.Address, PosOfColon - 1)
Cell2 = Right(rng.Address, Len(rng.Address) - PosOfColon)
If Left(Cell1, 2) = Left(Cell2, 2) Then
TotalCell = rng.Count
Dim i&
For i = 0 To TotalCell - 1
If Not IsNumeric(Range(Cell1).Offset(i, 0).Value) Then
GoTo 112:
End If
Cell2 = Range(Cell1).Offset(i, 0).Address
Sum = Range(Cell2).Cells.Value + ValueToChange
On Error GoTo 111
Range(Cell2).Value = Sum
GoTo 112
111:
MsgBox (Err.Number & ":" & Err.Description)
112:
Next i
Else
MsgBox ("Select Column only...")
End If
End Function
Then, go back to your spreadsheet and select your range with your mouse like this:
Ok, now hit ALT + F8 to View Macros and run the ChangeColumnValue macro.
You will be prompt for a Value to Change and all cells within selected range will be Increased/Decreased by that Value.
and your final result if you type 5 in the prompt box will look like this
Good luck!

Answer 2

finally here is the solution.
Sub ChangeRowValues()
Dim rng As Range
Dim R As Range
Dim ValueToChange As Long
Dim Cell1, Cell2 As String
Dim PosOfColon, TotalCell, Sums, i As Integer
Set rng = Selection
ValueToChange = Val(InputBox("Enter Number to Change:", "Enter Number...", 0))
PosOfColon = InStr(1, rng.Address, ":")
Cell1 = Left(rng.Address, PosOfColon - 1)
Cell2 = Right(rng.Address, Len(rng.Address) - PosOfColon)
If UCase(Left(Cell1, 1)) = UCase(Left(Cell2, 1)) Then
TotalCell = rng.Count
For i = 0 To TotalCell - 1
'To Chnage Values of Row....
Range(Cell1).Offset(0, i).Select
'To Chnage Values of Colum....
'Range(Cell1).Offset(i,0).Select
If IsNumeric(ActiveCell.Value) = True Then
ActiveCell.Value = Val(ActiveCell.Value) + ValueToChange
End If
Next i
Else
MsgBox ("Select Row only...")
End If
End Sub

range() function input is cell address, for example, range(a1:b2;g1:h4), you cannot input some result in it.
