    passing variable to javascript

    Hi,
    I am new to JS and PHP, hope someone can give me a hint. I am writing a PHP session that uses a java script count down timer. I dont think I am passing the variable right, here is my code:

    <form name="Tick">
    <input type="text" size="11" name="Clock">
    </form>

    <?php
    session_start();
    if (!isset($_SESSION["minutes"]) && !isset($_SESSION["seconds"]))
    {
    $_SESSION["minutes"] = 12;
    $_SESSION["seconds"] = 0;
    }


    <script type="text/javascript">
    var minutes = $_SESSION["minutes"];
    var seconds = $_SESSION["seconds"];

    function display() {
    if (seconds==0) {
    seconds=59;
    minutes = minutes-1;
    }

    if (seconds<10)
    {
    document.Tick.Clock.value=minutes+":0"+seconds;
    setTimeout("display()",1000);
    }
    else
    {
    document.Tick.Clock.value=minutes+":"+seconds;
    setTimeout("display()",1000);
    }
    seconds=seconds-1;
    }
    display();
    $_SESSION["minutes"] = minutes;
    $_SESSION["seconds"] = seconds;
    </script>
    ?>

    Thanks for your help.

    The browser sees only the javascript.
    Do a view source and see what you're getting. Post it here if you still can't tell what the problem is.
    If you get errors, it always helps to post them.

    If this post contains any code, I may or may not have tested it. It's probably just example code, so no getting knickers in a bunch over a typo, OK? If it doesn't have basic error checking in it, such as object detection or checking if objects are null before using them, put that in there. I'm giving examples, not typing up your whole app for you. You run code at your own risk.
