Passing the value of a ColdFusion variable to Flash?

In our current site stucture, we have a Gif “next” button whose <a href> value is dynamically created when the page loads by a ColdFusion variable.

The url I need to pass to flash is being held in a Cold Fusion Variable called “url” - when the page is created the value of “url” is passed to the <a href> tag of a static gif image.

I need to know how to pass the value of the CFM variable “url” to the getUrl action of a SWF button file as opposed to a gif.
