what's your array ?
usually you'll do a check before you're going in the loop, something like :
Code:
if(!empty($array) && is_array($array))
{
foreach()...
}

Please use [CODE] tags when posting code and make a comment at the
line you have the error - in your case line 68. Otherwise it's hard
to find the right place to look for your error.
