This seems a scope problem at first look. You declare the exception inside the begin-end block in the procedure, but your "exception when" clause is outside the begin-end block.

Subject: PL/SQL exceptions handling help  

I've spent all morning R'ing the FMs and looking up examples and I still can't get my PL/Sql to handle my user-defined exception. Obviously I'm missing something that is clear as a bell to all the people who post these examples. Any idea what it is?
