Hi I need to specify the columns of a Spreadsheet using arguments. This is what I need:

("B2:B38,C2:C122")

And this is what I have

Code:
Dim Columns As String
CellEnd = 122     
CellBeg = 38

Columns = (("B" & CellBeg & ":" & "B" & CellEnd)) & _
          (("C" & CellBeg & ":" & "C" & CellEnd))
When I execute this line the result is Columns = ("B2:B38C2:C122")
I DO NOT get the coma in between and that is giving me an error. What will be the right format to get this right? I am still trying to solve it.
Thanks
