Before we even discuss the logic of your code, I need you to confirm that you are 1) properly quoting your attributes (some browsers will react badly if you don't) 2) not using the actual value "checkbox[$artID]" in your code With "2", in other words I am making sure you are not trying to pass an array element name via HTTP. The name of any HTML form input needs to be made up of letters, underscores, and numbers, IIRC. As far as the logic goes, forgive me for being blunt but your explanation is confusing me and I can't really follow it. If you have neat, commented code, post the relevant part of it and hopefully someone can come up with some good input (I'll take a stab). Basically checkboxes are tricky, because if a checkbox is NOT checked, and then the form is submitted, an empty variable name is NOT sent... only checked boxes are sent. So you need to check for the presence of variables if you are going to unset() the unchecked boxes, or determine the unchecked values based on what is NOT checked, etc. Good luck Erik ---- Erik Price Web Developer Temp Media Lab, H.H.
