Retrieving an Record Problem

Okay, that may not be the best subject...

I am setting up an approval workflow within an application. I pass the
username and the dollar amount to the subprocedure and figure out what
workflow I need to use for the approval process. I thought I had this
working until I try to handle the condition when the user hasn't been setup.

So in my table I have:
wfid wfuser wfamt
1 user1 0
2 user2 0
2 user2 10000.00

Now if user3 tries to send something to the workflow, it shouldn't go
becuase they are not setup. (Please note I have another table that contains
the actual flow definition)

I had this code to retrieve the correct workflow:
setgt (userId:amount) ARWFR1;
readp ARWFR1;
return wfid;

Obviously this works if the user is properly setup. However, throw our user3
sinareo back in and it won't work right. So then I tried:
setgt (userId:amount) ARWFR1;
readpe (userId) ARWFR1;
if (%eof());
return 0;
endif;
return wfid;

This is not working as I had expected. I am sure I am missing obvious, can
you see it? I hope my current logic is clear enough.
