Onload of popup do this:
window.opener.document.parentformname.hiddenvariablename.value = document.childform.a.value;

<form name=&quot;form_1&quot;>
<input type=&quot;text&quot; name=&quot;value1&quot; value=&quot;MyNiceLittleValue&quot;>
</form>

<p>

<script language=&quot;JavaScript&quot;>
<!-- hide me
document.writeln(document.form1.value1.value);
// show me -->
</script>

Gives the error: &quot;document.form1 has no properties.&quot;


Anybody know why?

Good Gravey. That's just a bit embarrassing...

Also, I've found the javascript MUST be below the form. Otherwise it will not work at all.

Happy hunting.
