About the first problem of the form not being submitted all you have to do is

1. remove the onclick handler from the input tag

2. Edit the file where your post variables are being submitted to. Note that your must first process the post array - $POST[] before making any redirects

3. At the point where you've finished processing your POST variable then you can add the redirect script like this:

?>
<script type='text/javascript'>
window.location="url";
</script>
<?php

note: the first and last line is only needed if you need to break away from any php or server side scripting before making the redirection.

As for the ajax. It'll take some time to go through your code to find the bug. But i usually recommend some third-party interface in dealing with the intricacies of ajax. Try googling up YUI-Yahoo User Interface. That what i use personally.

Anyways, i'll still go through your code
