input box and onchange help needed

OK, can someone tell me what I am doing wrong...

<form name="form1" method="post" action="<?php echo $PHP_SELF; ?>">
<input name = "zipcode" size="10" value="<? echo $zipcode; ?>" onchange="return chk(this)">

</form>
<script language="Javascript">
function chk(frm)
{
frm.form.submit();
}

</script>

All I want to do is when they enter a value it updates the other fields.

the code you have doesn't update any field.
it just submits the form on click

ok so how do I do this using javascripts?

What exactly do you mean by "updates the other fields"? What other fields? What do they look like when you've updated them?

It looks like you're just trying to submit the form "onchange". That's easy enough but you'll still need a submit button for we who do not use JavaScript.
