Javascript Form Validation - Form Action To Another Page

In my prototype asp page (with no javascript and no password validation, I have a registration form with the following action:

<form name="form" method="post" action="RegDetails.asp">

This works fine, the form details are collected by RegDetails.asp

I am attempting to include javascript server side validation for the pasword, which obviously requires password and password2 fields (to be verified). I have used the script available at:

http://javascript.internet.com/forms/val-pass.html

It works fine in a new blank page with the form action:

<form name=myForm onSubmit="return validatePwd()">

The final stage in this javascript demo form displays an alert box:

else {
alert('Nice job.');
return true;


When I change the first line of my original form to:

<form name=myForm onSubmit="return validatePwd()">

how do I get my original action of - action="RegDetails.asp" instead of this alert box?
