if $code['assign'][$i] has some integer value, then it is not an array. if $code['assign'][$i][$j] has some integer value, then $code['assign'][$i] is an array. You have two mutually exclusive possibilities there. Probably, what you want to do is something like: $code['assign'][$i]['aid'] = (assign ID); $code['assign'][$i][$j] = (whatever you want here); (which, for simplicity, translates into something like:) $code['assign'][1]['aid'] = 1; $code['assign'][1]['1'] = 11; $code['assign'][1]['2'] = 12; $code['assign'][1]['3'] = 13; $code['assign'][1]['4'] = 14; $code['assign'][1]['5'] = 15; etc. -- Rob > codeapply ID on the assign ID). > > Thanks in advance! -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
