I am attempting to set up a workflow/custom function for the automatic creation of a customer payment and sending the email receipt, but am receiving the error "Improper Statement Error might be due to missing ';' at end of the line or incomplete expression"

I've been over everything several times and cannot see where the error is (code is copied into the attached document).  I haven't used custom functions before with Deluge, so it's very likely something very simple, or I've completely mucked something up.  Any help would be greatly appreciated.
