sending Var values to a new swf

Here's the plan:

I'm developing a flash application, which gathers options for an electronic rack enclosure. Once all 16 options are chosen I want to generate a datasheet based on the customer’s choices.

He hits a button, a new window pops up with a flash SWF that grabs all the variables and populates the datasheet. It will have to be a new SWF as the size will be drastically different for a printable datasheet.

Is there an easy way to pass along the Var values, or am I looking at some kind of server side programming?

Thanks!
