I need to compare two cells on the same worksheet. If they are not equal when the user saves I need to throw an error message. Is this even possible?

Thanks,

Brad,

Just add the following code in the thisworkbook module of your workbook, It will throw a error message when you try to save the workbook if sheet1 CELL A1 Value is not equal to shee1 Cell B1 Value.

To open the vb editor, press alt+f11 over your workbook which will open the vb editor then crtl+r to view the project explorer and then the code goes to thisworkbook module...

Saurabh...

Private Sub Workbook_BeforeSave(ByVal SaveAsUI As Boolean, Cancel As Boolean)
    Dim WS As Worksheet
    Set WS = Sheets("Sheet1")
    If WS.Range("A1").Value = WS.Range("B1").Value Then
        MsgBox "You cant save this workbook till the time Sheet1 A1 Value is equal to B1"
        Cancel = True
    End If
 
 
End Sub

Here is an example. switch the value of either B3 or B5 and save, you will see the error message.

I tried to put these in my workbook, but for some reason they will not trigger when I try and save. What am I missing?

Thanks,

Brad
