Hi!
I am having a problem trying to pass a hidden varibale (php generated) into a javasrcipt event (self.location)shown below.
the values dd3.php?cat=val&appid=appidcheck do show up in the url
eg:
localhost/dd3.php?cat=1&appid=8 appears in the url but the values: cat=1 and appid=8 are not submitted into the actionpage (dd3.php).
my guess is that problem originates from:
"self.location="
is there any javascript which allows the action page to accept the passed variables contained in the url?

thanks in adavnce!!!

Code:
<SCRIPT language=JavaScript>
function reload(form)
{

var val=form.cat.options[form.cat.options.selectedIndex].value; 
self.location='dd3.php?cat=' + val +'&appid=' +  <?php echo $appidcheck;?> ;
}
function reload3(form)
{

var val=form.cat.options[form.cat.options.selectedIndex].value; 
var val2=form.subcat.options[form.subcat.options.selectedIndex].value; 
self.location='dd3.php?cat=' + val + '&cat3=' + val2 +'&appid=' + <?php echo $appidcheck;?> ;
}

</script>
