Hello, I'm a beginner at using Excel macros, and after much cursing I was
finally able to get two macros to run on the same workbook. The one I'm
having trouble with takes the data from a particular cell and uses it to
rename the file before saving it. The problem is, both macros are still
active when opening that new file. This is for invoices. The initial file
is a blank invoice where I want the macros to run. The secondary file is
saved as the customer's name. I do not want the macros to run on the
secondary file. What can be done to auto-disable the macros on the new file?
(These are both auto-run macros.)

Thanks,
Duane

'invoice number advance
Private Sub Workbook_Open()
Range("m3").Value = Range("m3").Value + 0.1
End Sub

'auto filename change
Private Sub Workbook_BeforeClose(Cancel As Boolean)
ThisFile = Range("D13").Value
ActiveWorkbook.SaveAs Filename:=ThisFile
End Sub
