[SQL] Hrm...why is this wrong?

[Ken Corey]

In trying to use a plpgsql stored proc, I'm getting an error I don't 
understand.

When the select at the bottom of this email is executed, I'm getting the 
message:

ERROR:  parser: parse error at or near "$1"

Any ideas? <Gads I hope it's not something amazingly simple, but I'm sure it 
is...;^>
