    Display 3 records at a time

    I'm trying to display the newest 3 news posts and than give the user the option to press a button to display the next 3 and so on
    I've been at this for hours and I'm pretty sure my php is good i think I'm getting confused with the action script on the button so ill post both my php and button code see if anyone else has a fresh view

    $records_displayed = 3;
    if ( !isset($low)){
    $low = 0;
    if (!isset($high) ){
    $high = $records_displayed;
    $conn = db_connect();
    $sql = "SELECT * FROM news_post ORDER BY id DESC";
    $max_results = mysql_query($sql, $conn) or die(mysql_error());
    $count = mysql_num_rows($max_results);
    print "&max_records=";
    print "$count";

    $sql = "SELECT * FROM news_post ORDER BY id DESC LIMIT $low, $high ";
    $result = mysql_query($sql, $conn) or die(mysql_error());

    if (($low < 0) || ($low > $count)){
    print "&left=No More Entries.";
    else { print "&left=";
    print "&news=";
    while ($newArray = mysql_fetch_array($result)) {
    // give a name to the fields
    $id = $newArray['id'];
    $name = $newArray['name'];
    $headline = $newArray['headline'];
    $post = $newArray['post'];
    $date = $newArray['date'];
    print "<P><b><font color=\"#000000\">[$id] $headline <br> <font color=\"#CC6600\">$post <br><font color=\"#000000\">By: $name Posted: $date <br><font color=\"#CC6600\"></P>";

    on (press) {

    low = Number(low)+Number(3);
    high = Number(high)+Number(3);
    loadVariables("http://MYSITE/MYFOLDER/news.php?low="+low+"&R="+random(999) , POST);


    I don't get any errors just nothing happens when i press the button
    and as u can see in the php code i added prints to make sure the data was even spitting out
    Thnx in advance

    this does not look basically wrong...
    First of all, there is
    etc. in your php rather than $_REQUEST['low']
    This means you either need to have a very old php version running, or one where the server config still allows globals (some servers do for existing clients, just to not disrupt their scripts)
    Upload a file with
    <? php_info(); ?>
    to your server and watch it in the browser. Look for a setting called "register_globals". If that is not the problem, just view the news.php url in browser - any error messages?

    Things that you might want to improve:
    a) there does not seem to be any post data, since all the info is part of the url. Why not use GET?
    b) mysql has
    select count(*)
    to get the number of entries.
