Insert Row on Multiple Sheets - Copy Formulas

Hi all,

I'm new to the forum and have searched and found similar problems, but no solution meets my specific need. I have 3 sheets in a workbook which all follow an identical format (customer name in column A, and months in columns to the right (currently B through P - but this will increase with time). All of the names across the 3 sheets are in an identical order, but whenever I need to add a customer (which would be accomplished through inserting a row), I would like the other two sheets to update with the same customer name and copy the formulas in column B and right down one row to the newly inserted row. One caveat, the formula that the macro would copy is one that I created (it is not standard in excel - the formula adds only BOLD numbers)...

My sheet names are "Done & In CORD" "Done Not Received" and "Opportunity"

Here was my first crack at it...

Sub Insert_Rows()
    
    Dim sh As Worksheet
    
   
    For Each sh In Sheets
        If sh.Name = "Done & In CORD" Or _
            sh.Name = "Done Not Received" Or _
            sh.Name = "Opportunity" Then
            With sh
                .Cells(ActiveCell.Row, 4).EntireRow.Insert
                .Range(.Cells(ActiveCell.Row, 1), .Cells(ActiveCell.Row, 4)).FillDown
            End With
        End If
    Next sh

End Sub

Thanks for the help!
