I was pointed to this macro:

Public Function AllSheetNames()
Dim Arr() As String
Dim I As Integer
ReDim Arr(Sheets.Count - 1)
For I = 0 To Sheets.Count - 1
Arr(I) = Sheets(I + 1).Name
Next I
AllSheetNames = Arr ' return a row array OR
AllSheetNames = Application.WorksheetFunction.Transpose(Arr)
' return a column array
End Function

I can't seem to get it to work in my workbook.

Can someone walk me through the steps.

Thank you in advance.
