Interfacing with SWF movie not working with firefox

Hi Guys,

I want to use a flash input field on my web page, rather than a normal HTML textfield because I can add HTML styling to the contents.

So I have embedded my SWF movie into my web page and have used the ActionScript ExternalInterface to 'talk' to the rest of my website for which I'm using javascript. So basically all I want to do is at a certain point, press a button and the text content of the SWF movie (input box) will get assigned to a javascript variable which I can then use.

I have implemented this have tested it by just getting the contents of the input box to appear in my html paragraph with the id 'para'. It works if I am using IE and opera, but not with firefox, which I find very strange. I wonder if anyone can see where I am going wrong.

Here's my HTML code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en">
  <head>
    <title>FlashField</title>
    <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
    <script type="text/javascript" src="swfobject.js"></script>
    <script type="text/javascript" src="flashfield.js"></script>

</head>
  <body>
    <div>

<param name="movie" value="FTFTest2.swf" />
        <param name="scale" value="noscale" />
        <param name="allowscriptaccess" value="always" />
        
        <object type="application/x-shockwave-flash" data="FTFTest2.swf" width="350" height="40"
                scale="noscale" allowscriptaccess="always">
        
          <p>Alternative content</p>
        
        </object>
        
      </object>
    </div>

and here's my javascript code:

and finally, here are the relevant parts of the actionscript code:

Many thanks
