Question

This question was asked and answered back in 2010 but when I follow the directions of the venerable Mr. Buggabill and then run the macro (by editing the target cell) Excel promptly crashes. The code looks like this:

Private Sub Worksheet_Change(ByVal target As Range)
    If target.Address = "$A$1" Then
        ActiveWorkbook.Worksheets("Sheet2").Range(target.Address).Value = target.Value
    End If
End Sub

I created one version of the macro under Sheet1 (which pushes the target value to A1 on Sheet2) and another version of the macro under Sheet2 (which does the reverse). With only one macro in place this works fine but my intent is to be able to enter a value on either sheet and have the new value propagated into both input cells. Excel crashes because it’s a circular reference, right? Is there a way around this?

Answer 1

I suspect that it’s not a circular reference, but rather a stack overflow 😉

You might consider turning off eventing inside the execution of your macros.

Application.EnableEvents = False
...
Application.EnableEvents = True

This way, the other event handler won’t get called when you’re poking values onto the other sheet.
