PHP | Flash Query String

Hello, I have a button flash file. This file needs two parameters that are passed in through the query string. Here's my query string. navButtons.swf?myURL={$menu_channel_id[menu]}&buttonLabel={$menu_text[menu]} here is the URL that is being passed in domain.com/index.php?c=21&a=35&w=2&r=Y the ampersands are making flash think these are separate variables to pass into flash. Is there a way to make flash send in the above link as a whole without chopping it up into several separate variables. I would use some other method besides a query string but, I really need this to work with it. Hope that makes sense! Thanks, T
