Lynn,
There is worksheet event code associated with that sheet, in the worksheet code module, that controls that action. The code has cell reference at two points, one where the price and loabour data is cleared on a change of Category
If Not Intersect(Target, Me.Range("B15:B42, B66:B93")) Is Nothing Then
ElseIf Not Intersect(Target, Me.Range("C15:C42, C66:C93")) Is Nothing Then
I just changed these to
If Not Intersect(Target, Me.Range("B15:B42, B66:B93, B117:B143")) Is Nothing Then
ElseIf Not Intersect(Target, Me.Range("C15:C42, C66:C93, C117:C143")) Is Nothing Then
respectively to accomodate the new page.
If you add another, you can extend in the same way.
I hope your sister is doing well and on the raod to recovery.
