    Turn on display_errors and set your error_reporting to E_ALL and you should see an error message about ‘headers already sent’ – you have to call setcookie() BEFORE ANY HTML IS SENT. From php.net/setcookie:

    setcookie() defines a cookie to be
    sent along with the rest of the HTTP
    headers. Like other headers, cookies
    must be sent before any output from
    your script (this is a protocol
    restriction). This requires that you
    place calls to this function prior to
    any output, including and
    tags as well as any whitespace.

    In the code block that you posted this bit:

    <script>
function Redirect(url)
{
 location.href = url;
}

</script>

    Is being output directly to the browser well before you ever attempt to set the cookies.

    Your two possibilities would be to use output buffering so that you output everything at the very end or to switch to a method where all of your processing code is executed first in one script and there you set $_SESSION and cookie values and then include a second script at the tail end of the first that contains the code to be output to the browser.
