First I recommend you send a blank email to
[EMAIL PROTECTED] and join JS-Jive, the javascript list.
You'll get lots of help with Javascript.
But to answer your question, you need to access the selectedIndex property
of a select box to validate it....
<script>
function validateSelect(){
if (document.form.fieldname[selectedIndex].value == ""){
alert("Please select an option in the select box.");
return false;
}
}
</script>
onsubmit="return validateSelect()"
This assumes that you have an option in the select box with an empty
value...
<option value="">(select option)

I have added validation (shown below in the js) for the two text input
fields but need to build in validation for the two select boxes and also a
CFFile field as these are required fields in the form, any ideas on how to
integrate this into what I have below?
