Re: Displaying array of elements problem

first, set up the array something like: $artist("Bon Jovi","N\'Sync","Boyzone","Britney Spears","Jethro Tull", "Crosby\, Stills & Nash"); // note escape slash before single quote and comma I think they'll be needed, but maybe not. then set up your checkbox array something like: <?php print <form action=test.php method=GET> for ($i=0;$i<=count($artist)-1;$i++) { print "<input type=checkbox name=artist[$i] value=\'$artist[$i]\'>$artist[$i]"; // The escape slashes are important here } print <input type=submit name=submit> print </form> if (isset($submit)) { for ($i=0;$i<=count($artist)-1;$i++) { if (isset($artist[$i])) print $artist[$i]; if (isset($artist[$i])) $number=$number+1; } print $number; if ($number=="0") die ("go back and select something"); / / or do something else here. } The above is untested especially the array set up, but the rest should give you a hint on how to do what you want.
