    The code is ran before countbox is initialized. You need to run it after the page has loaded.
    [code]

    function DoGetCount()
    {
    GetCount('<?php echo $year; ?>','<?php echo $month; ?>','<?php echo $day; ?>');
    }
    window.onload=DoGetCount;

    [/code]

    Hello,

    anthrax11 is right. Your code is running before the initialization the countbox. First you declare the variable and then declare the values.
