I have this macro, which I got from some guru in this database a few years
ago, which has always worked, and but won't work in the spreadsheet I'm
working on today. The macro inserts a blank row wherever there's a change in
whatever column you select. The column I'm selecting has data that sometimes
starts with a number, sometimes with a symbol, sometimes with a letter. Is
it because of that that this macro won't work?

Sub InsertRow_At_Change()
Dim i As Long
Dim colno As Long
colno = InputBox("Enter a Column Number")
With Application
.Calculation = xlManual
.ScreenUpdating = False
End With
For i = Cells(Rows.Count, colno).End(xlUp).Row To 2 Step -1
If Cells(i - 1, colno) < Cells(i, colno) Then _
Cells(i, colno).Resize(1, 1).EntireRow.Insert
Next i
With Application
.Calculation = xlAutomatic
.ScreenUpdating = True
End With
End Sub
