Newbie Q:"RETURN cannot have a parameter in function returning set"?

Just did a LAPP install, FC4, A2.0.54, PSQL8.0.3, PHP5.0.4 and I'm using
pgAdmin III on my WinXP desktop.

Ported a database from a system running PostgreSQL 7.4.2 and after a few basic
tweaks I'm getting the error below. I've done a little RTFM and
Googling but so far
no results. Any pointers on the error or where to RTFM it welcome,
thanks in advance!
