How to fix jQuery/PHP form submission? - php

Question

I am updating a client site and the simple contact form that used to work is now broken. It appears that the HTML form sends and receives data from the jQuery file as I get the error messages returned, though it is not passing the data through to the PHP file for sending an email. If I send the data direct from the HTML form to the PHP file, then an email is sent. The error is probably at the end of the jQuery, though my search for how to fix has not revealed an answer. Any ideas on how to make this work?
HTML Form
<form id="rsForm" action="#" onsubmit="return goContact(this);" name="rsForm">
<input id="formNam" type="hidden" name="formNam" value="3" />
<div class="CU_row">

<div class="CU_form_entry"><input id="firstName" maxlength="120" size="39" name="first" type="text" /> <span class="redT">*</span></div>
</div>
