Simple Script runs on IE and Chrome but not FF

Posted 02 September 2010 - 12:52 PM

Hello, I am fairly new to javascript but I have some programming experience. This simple javascript will run on IE and Chrome just fine, but if I try to run it on Firefox it does nothing. If I check FF error console it says 'form1 is not defined'???!!!! I have written this if condition about 20 different ways and it usually runs on IE and Chrome but not FF, getting flustered with it. Oh and if I remove the if clause it will show the alert box on FF, so the problem lies in the If statement. Why would this cause errors with FF? Thanks :bigsmile:

<script type="text/javascript">
function show_alert()
{
    if (document.form1.CheckboxGroup1_0.checked == true)
    alert("I am an alert box!")
}
</script>
