    Thanks. Not sure why I'm getting an error on the substring function.

    Msg 8116, Level 16, State 1, Line 1

    Argument data type numeric is invalid for argument 1 of substring function.

    With no ddl we are shooting in the dark but that message is pretty clear. Your code "substring(Customer.STARTDATE, 3, 2)" make me guess that STARTDATE is a datetime? You can't take a substring of any datatype other than character data. You should probably take a look at CONVERT and/or DATEPART.
