A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
The following Macro will auto insert the template sheet and assign it a number. You may have a shortcut for the macro. Hope you are using VBA, otherwise post back for a more detailed explanation.
Sub Macro1()
Dim MaxNum As Integer
Sheets(Sheets.Count).Select
MaxNum = ActiveSheet.Range("F8").Value
Sheets.Add After:=ActiveSheet, Type:= "C:\Program Files\Microsoft Office\Templates\1033\BillingStatement.xltx"
ActiveSheet.Range("F8").Value = MaxNum + 1
End Sub
All you need to do is change the path to the path of your template and change the cell reference F8 to whereever your autonumber lies.
Hope this helps.
