At line 36 add:

or die(mysql_error());

and see if it returns some information about the query syntax. By the way, you should switch to MySQLi or PDO. The mysql_* functions have been removed from PHP 7.0, so you will have hard time when upgrading. See:

You have a form inside another form - may not correctly treated by browser

You say it isn't working, but is it writing any errors to the error log or output on the page?
