It can be a little simpler if you have many boxes, using PHP's "variable variables", like: for ($c=1; $c<=$numboxes; $c++) { $varvar="box$c"; if ($$varvar) { } } This is if you know how many boxes (numboxes) you had, to start with. If you don't, use a while instead. This way you can effectively handle parameters array-like. Regards, Gonzalo.
