This should have worked. Review it and see what is in $_POST with: <?php var_dump($_POST);?> > Neither does just saying $_POST['re_reference_id'] = $re_reference_id. You can do that in the first script, but it won't affect the next one. And it's probably a Bad Idea to cram things into $_POST or other built-ins, as a matter of style. > Probably I should be using session variables here.

You would have to be sure that you give meaninful shelf-life and names to the data you choose to put in $_SESSION, and not twist yourself into knots by snarling up your own data... But it works a treat if you plan that part out. -- Some people have a "gift" link here. Know what I want?
