Just a suggestion for troubleshooting. Especially since you may not have access to server logs. Try taking the logic you are using and putting it into a script you can run from the commandline to make sure the logic works the way you expect before putting it into the CGI script. Once you get that working (and know it works their), then put it back in and test it with the CGI app. I've often found simplifying a script will help get to the root of the problem and a fix is fairly apparent at that point. Adding use strict and use warnings in the test script will also help. Hope that helps.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
