checking if checkbox is set to true

[Peter]

Hello I'm trying to create a script that checks to see if any of the
checkboxes are set on a onSubmit.

For some reason it never returns a value of true of false.

here's the script:
<script language="javascript">
function confirmCancel(ticketcnt)
{
var retVal = false;

for (x = 0; x <= ticketcnt; x++)
{
var cancel_fld = "cancel" + x;

if (document.getElementById.(cancel_fld).checked == true)
{
retVal = true;
}
}

return retVal;
}
</script>

here's how i call it

<form name="CancelCMTicket_frm" action="cancelCMRec.php" method="post"
onSubmit="return confirmCancel('3')">

The last line return retVal. retVal variable never gets set.

I'm stuck on this one, can anyone give any advice.

Thanks
Peter

getElementById() is not an attribute but a method. Remove the dot before
the parenthesis. Also, the "== true" comparison is redundant (not a
problem, though).

Do you use Firefox's JavaScript console? Using non-existent attributes
always raises an error.
