I'm trying to create a contact form at www.mauitradewinds.com/RezEasy/contact.html    There is javascript which reminds the visitor to complete four required form fields before submitting the form.  The last required field is "message", but entering a message doesn't satisfy the validator, which pops up an alert.

I'd appreciate guidance on two items:
1. Getting the validator to accept a message; and
2. Changing the alert popup so that it is more informative.

You can't check a 'textarea' with just 'form.message.value.length'.  I think your syntax is wrong.  In my working pages, I use something like "document.forms.EmailForm.message.value.length".

Some info here also: http://www.w3schools.com/jsref/coll_doc_forms.asp

YOu can also use the 'id' to check it and this is what I use on another page.
function checkit() {
        tx = document.getElementById("tarea").value
        txl = tx.length;
				form.message.value.length==0
        alert(tx+" is "+txl+" chars long.");
        if(txl<4) return false;
}
