You should learn how to debug your own code. Teach a man to fish versus
teaching a man how to fish and all. The tools (specifically breakpoints) you
will need are described in this section of the documentation:

If during the course of your own debugging you have SPECIFIC questions
please ask those in the newsgroup.
