Variables in JS/HTML not getting passed to SWF on 1struntime.

I'm having an issue with getting variables to pass from a query string, to
JS/HTML, to Flash on 1st runtime; 2nd, 3rd, ..., Nth runtimes work fine.
Here's a the step-by-step explanation of how I am doing this:

[bullet]Starting out on the
http://www.deforestarchitects.com/pages/clients.htm page, if you click on one
of the "See their project" links, it should take you to a project page that
hosts a SWF file that will then display the correct, corresponding project for
that client.[/bullet]
[bullet]When the "See their project" link is clicked, it will then direct you
to a page, but appending a variable in a query string (i.e.,
http://www.deforestarchitects.com/pa...ject=fairhaven). [/bullet]
[bullet]This variable is then passed to the object, param and embed tags by
appending document location search after the *.swf in the param value and embed
src properties.[/bullet]
