ActionScript 2.0 :: Change Browser Window Title?

I cannot seem to get the following to work:

In flash (as2):

Actionscript Code:
getURL("JavaScript:changeTitle('Hello!')");

in browser:

PHP Code:

<script language="javascript">
<!--
function changeTitle(t){

[Code]....

The result is - the page title stays the same, there are no errors - but i do get an alert that says "changed! Hello!" So the function is being fired, and the variable is being sent. It just will not change the page title.

If i call the function in javascript - so just under the function add - changeTitle("good") - it works fine, changing the title.
