I am trying to only run a set of macros if a sheet doesn't already exist. I have a macro that creates a sheet and combines data from two sheets into it, and another that formats the new sheet. Since it needs to run on workbook open, I can't have it recreating the sheet again and again. I have been trying the following, but it gives the error: "sub or Function not defined":
Private Sub Workbook_Open()
If SheetExist("MyNewSheet") Then
End Sub
Else
Combine
Format
End Sub
