Where is "valdate()" defined?
And your spelling of "maxlength" is wrong.

There are no javascript functions defined on/or linked to your page.

You are programmaticall y calling Form#submit() from a submit button!

Why would ever feel the need to do this, an <input type="submit" SUBMITS
THE FORM. You don't need to include ONCLICK="...sub mit the form...", it
ALREADY KNOWS HOW TO DO THAT.

Not only that, but programmaticall y calling Form#submit() does _not_
call the onsubmit event of the <form>, so your validation code _never
runs_.

<input type="submit" value="Submit"
onclick="this.v alue='Please wait...';this.d isabled=true;re turn true;">

Please note that the -disabled- property takes a boolean, not a string.

By the way, if the user clicks Stop before the form gets navigated away
from, or the form submission fails for some reason, you've left the user
with a form that can not be re-submitted. One possible (but not
necessarily the correct) solution to this is:

<form name="myForm">
<input type="submit" name="mySubmit"
value="Submit"
onclick="
this.value='Ple ase wait...';
this.disabled=t rue;
var t = setTimeout(
'(sub=document. forms[\'myForm\'].elements[\'mySubmit\']).disabled=fals e;sub.value=\'S ubmit\';',
5000
);
return false;
"[color=blue]
>[/color]
</form>

This restores the submit button to working state after 5 seconds.
