problem w/plpgsql proc

Hi all - This might be the wrong forum for this, but I don't want to cross-post 
unless someone tells me I should.

Anyways, I'm having a problem trying to compile this plpg proc. I'll post 
the proc and the errors. I'm coming from a T-SQL background, so hopefully 
when I get the hang of Pl/PgSQL I'll be able to draft up a doc for porting 
from T-SQL to Pl/PgSQL.

proc:
/***editEmail: all vars required  - will renumber the sequence if needed - if the email address is not found, it will
addit.       returns:               -1 - the user already has 8 entries               0  - the record was updated, and
thetable renumbered               1  - the record was added.**/

this is part of a larger script, but the function declaration before this 
works perfectly, so I assume the problem lies here.

sorry for the length...
TIA
