I'm having some trouble with a bit of js in an onchange event. Basically, if someone changes the Pno field, i want to send the new value of Pno to a second form, the submit that form. I've done this bazillions of times before, i know it works... but it won't It keeps giving me a 'null or not an object' error for the "document.getElementById('claimstart').Pno" part...
<form name="claimlayer" id="claimlayerform">
<input name="Pno" value="1940B" onchange="document.getElementById('claimstart').Pno.value = this.value; document.getElementById('claimstart').submit()">
</form>
<form method="POST" action="form.asp" name="claimstart" id="claimstart" target="postwindow">
<input name="Pno" size="10">
</form>
any ideas why it's being a p


?
