Also you are missing a quote at the start of the value= (double quotes makes it easier to print in my opinion) It should be like this: while (!$recordSet->EOF) { print($recordSet->fields[0] . '<input name="interesses[]" type="checkbox" id="interesses" value="' . $recordSet->fields[0].'">' ); Then any checkboxes checked will be in an array called interesses $interesses = (isset($_POST['interesses']))? $_POST['interesses'] : array(); if(count($interesses) > 0){ //checkboxes have been ticked }else{ //none ticked } -- regards, Tom
