How come VBA excel keeps running the statement inside a conditional statement even if it is false? - vba

Question

I am trying to create an automatic filling of the payroll spreadsheet I created. However, no matter how much I try it the value of z = 1 all the time even if the logic returns FALSE values (I validated this using MsgBox).
My goal in this code is to check whether there is already a record in another sheet. If there isn't it will automatically add the record with the appropriate details based on the available data.
Below is the full VBA code (Note code is incomplete so it is a bit unpolished still):
Option Explicit
Public p As Long
Sub test()
Dim Total_rows_PR As Long
Dim Total_rows_DTR As Long
Total_rows_PR = Worksheets("Payroll - Regular").Range("B" & Rows.Count).End(xlUp).Row
Total_rows_DTR = Worksheets("DTR").Range("B" & Rows.Count).End(xlUp).Row
Dim q As Long
Dim j As Long
Dim z As Long
For j = 1 To Total_rows_DTR - 1
For q = 1 To Total_rows_PR + p - 2
If Worksheets("DTR").Cells(1 + j, 33) = Worksheets("Payroll - Regular").Cells(2 + q, 1) Then
If Worksheets("DTR").Cells(1 + j, 34) = Worksheets("Payroll - Regular").Cells(2 + q, 2) Then
If Worksheets("DTR").Cells(1 + j, 2) = Worksheets("Payroll - Regular").Cells(2 + q, 3) Then
z = 1
Exit For
End If
End If
End If
Next q
' Below is where the assignment should happen but only returns a blank cell
If z = 0 Then Worksheets("Payroll - Regular").Cells(Total_rows_PR + 1 + p, 1) = Worksheets("DTR").Cells(1 + j, 33)
If z = 0 Then Worksheets("Payroll - Regular").Cells(Total_rows_PR + 1 + p, 2) = Worksheets("DTR").Cells(1 + j, 34)
If z = 0 Then Worksheets("Payroll - Regular").Cells(Total_rows_PR + 1 + p, 3) = Worksheets("DTR").Cells(1 + j, 2)
If z = 0 Then p = p + 1
z = 0
Next j
End Sub
Update: I realized that even if the conditions are not being a met in the first portion of If-Then loops, the value of z is set to 1 for no reason. This is the reason why it won't assign values. However, I do not see why it keeps assigning to 1.

So the first image is where data is encoded (not shown in image because it is in the leftmost part of the spreadsheet, but basically it inputs the name of the person, date, and the daily time record (DTR) of the person). When the data is encoded, it will automatically indicate what month and year it is based on the helper column AG month and column AH for year. Somewhere in the start of the same worksheet at column B is where the name of the person is. All of these 3 will be used.
This second image is where the summaries are computed. If there is an entry for a specific person at a certain month and year and it is not located in this worksheet, it will automatically fill in that person's name as well as the month and year. Basically that's what the code i'm trying to create does.
The output is a fully automated spreadsheet that only requires data entry in the DTR sheet. All computations already have their corresponding formulas.

First: You have a really strange way of writing your if-statements.
I think what you mean is
For q = 1 To Total_rows_PR + p
If Worksheets("DTR").Cells(1 + j, 33) = Worksheets("Payroll - Regular").Cells(2 + q, 1) _
And Worksheets("DTR").Cells(1 + j, 34) = Worksheets("Payroll - Regular").Cells(2 + q, 2) _
And Worksheets("DTR").Cells(1 + j, 2) = Worksheets("Payroll - Regular").Cells(2 + q, 3) Then
z = 1
Exit For ' Once found, z stays 1 so you don't have to continue the inner loop.
End If
Next q
Second: I am not sure what exactly you want to achieve, but as far as I understand, your problem is that you are looping to far. At the last iteration of the outer loop, your accessing row 1 + j of sheet DTR which is empty at that time, and you are accessing row 2 + q (which is the same as 2 + Total_rows_PR + p) - also empty (and comparing the two emtpy lines sets z to 1).
A variable is never set for no reason. Is is maybe set and you don't understand the reason.
Debug your code step by step, watch where it behaves different as you expect and find the reason why it does what is does.
