Is something wrong with parenthesis or quotes? [PHP]

Hi guys i have a problem with this code link to the code

The problem (i think) is with quotes or/and parenthesis... (Error 500 on the server) ( Error on local server: Parse error: syntax error, unexpected T_IF on line 352)

The line 352 is that:

<?php } else if($_SESSION['lang'] == 'fra') { ?> and before these lines there aren't any forgotten semicolons ..could someone help me please?
