AddPerson fails if Group has no existing records

[gsmithosi]

I have an existing group in the AB that does not have contacts.  In FileMaker I have a contact assigned to that group.  I can create the contact properly and recorded the UID for the contact.  After adding the contact, i search for the group and perform the OpenFirstRecord step which obviously returns END.  As expected.  But when I attempt to AddPerson, I receive an error.  Unexpected. 

How can I add a new contact to a group that does not have existing contacts?

Found the problem.  Quotes were around the FileMaker field that stored the record ID.  Corrected and is working properly.
