forum 'reply to post' submission / redirection problem

forum 'reply to post' submission / redirection problem
Hey PHPers/SQLers, just finished getting some code working for a 'reply to a
topic in a forum' working but having some problems with the redirection when
actually submitting the post.

Basically this code has two sections;
One is to display the form to actually reply to the original post topic and
the second is to submit the information using the same page by checking a
hidden variable. If the hidden variable op is not "addpost" it will show the
form, if op is "addpost" it will add the reply to the database.

The problem I'm having is that when submitting the form, although the data
goes into the database just fine, and when refreshing the posts page it
shows up OK, it looks like the page is still doing something, with the
progress bar constantly refreshing.

There are no errors but I imagine it would be in the final block of code.
When clicking on submit in the form it does not appear to be reaching the
lines:

header("Location: displaytopic.php?topicid=$topicid");
exit;

I'm using Windows 2000 with apache 1.3, PHP 4 and MySQL 4.1

Actual code follows. I have included the entire block if it helps anyone
else with forum issues and to help anyone troubleshooting this issue. Thanks
in advance.
