Hi, 1) like Bastian already pointed out, you need to name your checkboxes "val[]" in order to have PHP recognize them being an array. 2) You cannot use "isset($val[0])" and "isset($val[1])". If any checkbox is clicked, $val[0] will always be set. If only one is clicked (regardless which one) index 0 will be set and index 1 unset. Instead, you should if(is_array($val)){ if (in_array('a', $val) && in_array('s', $val)) $eval='as'; elseif (in_array('a', $val)) $eval='a'; elseif (in_array('s', $val)) $eval='s'; However this would give you the very same result, but much more elegant: $eval = join('', $val); And it will automatically handle all further additions when $val[] might have more possible values except 'a' and 's'. -- >O Ernest E.
