Loop w/ Rows().Delete not working...

[MistakesWereMade]

I have a 'for loop' that is supposed to compare a cell in the master workbook with a set value, and then delete a row in the new workbook based on whether the condition is met or not. Currently, my loop runs and every row in the new workbook is deleted...

m is equal to 3 and the initial condition of Cell(n, 15).Value is 2.

If I set the if loops to "... <> m -1", the loop works fine for some reason and deletes every row that doesn't contain 2 in the new workbook. BUT, I need it to work with "...<> m" because m is a changing vector.

For n = ThisWb.Sheets(1).Cells(Rows.Count, 12).End(xlUp).Row To 2 Step -1
        
    If ThisWb.Sheets(1).Cells(n, 15).Value <> m Then
        wbTemp.Sheets(1).Rows(n).Delete
    End If
            
Next n

Seems odd that you check a row in the master book & then delete a row in another book.
That said, do you have any cells in col O of the Master that are exactly 3?

Yes, only 2s and 3s. And they are DEFINITELY exist.

I'm making a program to filter through thousands of data points and then store in a new workbook.

I just changed my code as shown below... It proves my m is equal to 3 since EVERY row in the new workbook was deleted. So I'm assuming my if statement condition is throwing me off somehow...

For n = ThisWb.Sheets(1).Cells(Rows.Count, 12).End(xlUp).Row To 2 Step -1
    If m = 3 Then
        wbTemp.Sheets(1).Rows(n).Delete
    End If           
Next n

That doesn't explain why you check col O in the master & then delete rows from another sheet, rather than checking the rows you are deleting.
Are the values in col O text or numbers?
Try filtering the Master for 3 in col O, are any rows visible?
