For some reason this will not work... my $_POST variables check for no form variables and display a form... if they choose an item from a select box it queries the database for a field matching the $_post var and builds a new form creating 8 separate $_post variables to check for.. so far it works except when selecting an item from the select box it will only display the first form when there are $_post vars present. I think I am missing something, could someone look over my code? Thanks in advance, Jas function vlans_dhcp() { $lvl = base64_decode($_SESSION['lvl']);

    if ($lvl != "admin") {
        $_SESSION['lvl'] = base64_encode($lvl);
        $_SESSION['msg'] = $dberrors[12];
        call_user_func("db_logs");
    } elseif ($lvl == "admin") {
        $_SESSION['lvl'] = base64_encode($lvl);
        if (($_POST == "") || (!isset($_POST['dhcp_vlans'])) || (!isset($_POST['sub'])) || (!isset($_POST['msk'])) || (!isset($_POST['dns01'])) || (!isset($_POST['dns02'])) || (!isset($_POST['rtrs'])) || (!isset($_POST['vlans']))) {
            create 1st form with dhcp_vlans as $_post var....;

            create 2nd form based on dhcp_vlans $_post var and create 8 different $_post vars...;

hi jas, the problem is, that your second form is only executed if your first condition is false (else if). but because of your or condition (||) only one of them has to be true. right? right! so it doesn't matter if your $_POST['dhcp_vlans'] is not set, when any other isn't set. a solution might be: <?php

        if (
            $_POST == "" ||
            (
                !isset($_POST['dhcp_vlans']) &&
                !isset($_POST['sub']) &&
                !isset($_POST['msk']) &&
                !isset($_POST['dns01']) &&
                !isset($_POST['dns02']) &&
                !isset($_POST['rtrs']) &&
                !isset($_POST['vlans'])
            )
        )

?> hth SVEN Yah I figured that out.. those operators always throw me off... Thanks again.
