Dynamic flash link ?
 

I've got this flash banner , but I'd like to be able to add dynamic links to it based on variables in the embed tag.

I've got access to the source but basically I'd like to be able to add on a referal id based on which ever affiliate is using the banner ,

So the banner would be linked to www.mysite.com

but affiliates can add their affiliate ID to the link via variables or the embed tag param names .. producing www.mysite.com/affid=1212 or something similar

Doesn't seem so easy :( Anyone know of any good tutorials , or know how it's done ?
