I think you're definitely at the "What is the question?" stage of Perl programming. Welcome.

If you are using CGI.pm you can use the delete_all() method to clear form fields:

# OO way
$q->delete_all();

# other, just
delete_all();

The question is then "How do I clear CGI parameters on processing a submitted form?".

Of course, that may not be the question. For future reference, I suggest you post code samples when asking questions, especially when you're unsure exactly what it is that you are asking.
