Ugh, I think I'm done for the day. header() requires output buffering which would span several files and sounds like another mess.

Well, for now, I set up some of the links to maintain the $pics variable in the url as a $_REQUEST and circumvented the header() mess with a url constructed from the returned $_REQUEST value that has to be clicked to proceed: http://hills.ccsf.edu/~pfurma02/index.php?SCREEN=settings.php&PICS=6 It works. The settings link is way at the bottom of all pages. and my code below: <h1>Change Settings</h1> <center> <div class="textbox"> <?php if (isset ($_REQUEST ['PICS'])){ $pics = $_REQUEST ['PICS'];} if ($_POST){

    if (isset ($_POST['thumbs'])){
        $pics = $_POST['thumbs'];
        print "<a href=\"index.php?PICS="
              .$pics."\">return to gallery index with ".$pics
              ." thumbnails per page</a> note that only the top logo home linkwill preserve this setting while navigating the site and visiting links from the navigation bar at the bottom will reset to default";
    }

} ?> <form name="mail" action="<?php SCREEN_DIR . "/settings.php" ?>" method="post">

          <label for="thumbs">number of thumbnails per page: </label>
          <input type="text" name="thumbs" id="thumbs" size="2"
                 value="<?php print $pics ?>">
          <button type="submit">OK</button>

</form> </div> </center>
