the action of the form is to post to another page:
<form class="NewFromBlank_sal01" id="SimpleContact_NewFromBlank_sal01" name="SimpleContact_NewFromBlank_sal01" method="post" action="TSearch.php">
change that to:
<form class="NewFromBlank_sal01" id="SimpleContact_NewFromBlank_sal01" name="SimpleContact_NewFromBlank_sal01" method="post" action="">
so that it will post to itself.
