Why Clear_Record or Delete_record don't work???

Question

In a pre-text item trigger I have a call to a procedure that checks to see if a bill has already been entered.
If it has already been entered, I want to clear OR delete the record.
Here's the section of code:
FOR v_procheck in c_procheck LOOP
s_exists := 1;
clear_record;
message ('This freight bill has already been entered.');
End Loop;
I've tried it with delete record too, but neither do anything at all. I get the message okay, and I don't get any errors.
I can clear or delete the record from the toolbar.
Please help.
Thanks.
Lesley.

Thanks for your reply.
That makes complete sense - but I wasn't getting any errors so it was baffling me. I removed the message and I still get no errors even with error trapping & displaying err_code, err_type etc. etc.
How can I get around this? I need to check a bill once the first 3 fields are entered - in order to prevent unnecessary data entry. Then I want to clear the form and allow them to start over.
I can't seem to find a way to do this. And to be honest I'm not exactly seeing clearly at this point!
Thanks for your help.
