Hi, thanks so much for the help. Something isn't working right for me. Here's the story.

Sheet1 has variable data. Sheet3 has static data and filter. Filter criteria on "Sheet3" comes from Sheet1. Sheet1 has data that comes from filtered results on Sheet3.

Sheet3 has code:

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
Range("A1:U14").AdvancedFilter Action:=xlFilterCopy, CriteriaRange:=Range("A22:U23"), CopyToRange:=Range("A25:U26"), Unique:=False
End Sub

It works great if I do anything on Sheet3. No problems. Thank you!

At first I had code on Sheet1:

Private Sub Worksheet_Change(ByVal Target As Range)
Sheets("Sheet3").AutoFilter.ApplyFilter
End Sub

Which resulted in the error "Runtime error 91, Object Variable or With Block not Set".

I changed the code based on comments to be:

Private Sub Worksheet_Change(ByVal Target As Range)
On Error Resume Next
Sheets("Sheet3").AutoFilter.ApplyFilter
End Sub

Now I don't get an error, but the data on Sheet3 and therefore Sheet1 don't change. In other words, the event of applying the filter to Sheet3 doesn't occur when I make a change on Sheet1. It doesn't matter if I hit <return> or click on another cell after changing the Sheet3 filter criteria cell that is set on Sheet1.

As an aside, I expect that if I wanted to have multiple cells on Sheet1 that caused filters on Sheets 4 and 5 in addition to Sheet3, I would need the code on Sheet 1 to read:

Private Sub Worksheet_Change(ByVal Target As Range)
On Error Resume Next
Sheets("Sheet3").AutoFilter.ApplyFilter
Sheets("Sheet4").AutoFilter.ApplyFilter
Sheets("Sheet5").AutoFilter.ApplyFilter
End Sub

Thanks again!
