Fix a Flash swf file to call JavaScript code on WordPress page

So I have an old Flash 6 swf file living in my media directory and the swf file need to call a JavaScript function on my HTML page.

Now on my old non-wordpress web site I just put the html and swf file in the same directory and this call from Flash always worked

javascript:top.fSendForm()

But now the swf file is in another location I don't know how to reference my JavaScript function.

HTML I am using attached.

This is probably quite a quick job for someone familiar with Wordpress an the document object model at play on a modern XHTML page.
