Flash and Java Script

I am having a problem sending input text from an input text field with flash.

My action script for my submit button is this:

on (release) {
getURL ("javascript:GuestEntry('" + GUESTCODE + "')");
}



And I have assigned my input text field the variable name "GUESTCODE".


And my javascript fuction is defined in my html:

function GuestEntry() {

if (window.varSubmit == false) {
window.varSubmit = true;

with (document.frmLogin) {

MODULE.value = "LOGIN";
ACTION.value = "GUEST";
action=PgmPath+'gr_default.pgm'; submit();
}
}
}


Everything works great in html, but I am trying to replicate this in flash. The submit button is calling the javascipt fuction but not passing the text entered from the input text field.

Any help very much appreciated !!!

Thanks,
Charles
