editrecord.php calls user's record

I want the editrecord.php file that is installed with site assistant to automatically call the user's record. I have a field named "Web User Id" that equals the $userName or AccountName I could do a find for, but I don't have a clue what php code I would need to execute the find or change the current recid.

Here's the code on the top of editrecord.php, if that helps
