it looks like some code was deleted from the page.
The code causing the error is lines 68 - 70:
<?php
} // ("".($Search1_BOSS_all) ."" > "0")
?>
the error is occurring because the corresponding opening if statement was removed. add this if statement before the opening body tag:
<?php
if ("".($Search1_BOSS_all) ."" > "0") { // WebAssist Show If
?>
