Check the code on your menu.php file. It looks (from the source code) that you may have some extraneous 'mysql free result' lines at the bottom of your page:
Your source code shows repeatedly:
<b>Warning</b>: mysql_free_result(): supplied argument is not a valid MySQL result resource in <b>/home/agricon/public_html/b/CSSMenuWriter/cssmw/menu.php</b> on line <b>104</b><br /><br />

Try removing the duplicated 'mysql_free_result()' chunks of code and see if that solves the problem.
