The reason is that: 1) unchecked checkboxes do not make it into php 2) because you're not specifying an index for the array (level[]), php will create it for you automatically So instead of using just name="level[]" specify the level explicitly: name="level[0]", name="level[1]", etc NB you should do the same for prob[] as well. Having done that then in your example you should get something like: $prob[0]: Problem one $prob[1]: Problem two $level[1]: High $prob[2]: Problem three $level[2]: Low NB that $level[0] is undefined. -- Jason Wong -> Gremlins Associates -> www.gremlins.biz Open Source Software Systems Integrators * Web Design & Hosting * Internet & Intranet Applications Development * /* Harp not on that string. -- William Shakespeare, "Henry VI" */
