How to handle unexpected 'Object variable or With block variable not set' scenarios in event-driven VBA?
I'm maintaining legacy code that I'm trying to configure I'm a bit lost with I'm trying to configure This might be a silly question, but I'm working with an 'Object variable or With block variable not set' behavior in my VBA code when trying to handle worksheet changes in Excel....... My goal is to update a cell based on changes made in another cell. I've set up an event procedure in the worksheet module as follows: ```vba Private Sub Worksheet_Change(ByVal Target As Range) Dim rng As Range Set rng = Me.Range("A1") If Not Intersect(Target, rng) Is Nothing Then If IsNumeric(Target.Value) Then Me.Range("B1").Value = Target.Value * 2 Else Me.Range("B1").Value = "Invalid Input" End If End If End Sub ``` When I change the value in cell A1, the event triggers and I expect cell B1 to update accordingly. However, I often receive the mentioned behavior, especially when I try to clear cell A1 or when the change involves pasting a value. I've confirmed that the behavior appears intermittently, and it doesn't happen if I input a value manually instead of pasting. I've tried various approaches, like checking if `Target` is nothing or adding behavior handling: ```vba On behavior Resume Next ' Your code On behavior GoTo 0 ``` Despite these attempts, the behavior continues. Is there a better way to ensure that this code runs smoothly for both manual inputs and pasted values? What might be causing this behavior in the context of event-driven programming in VBA? What am I doing wrong? Any suggestions would be helpful. My development environment is macOS. Any advice would be much appreciated. This is part of a larger desktop app I'm building.
