Flash Forms and Database Integration Question

So on this Flash Forms and Database Integration.

I have a var that is buried in flash, and I set it to a new var in the .asp page as follows:
strC1 = Request.Form("_level0.gamer.z0.loc")

That wont work. How do I reference that variable from .asp? Do I need to have Flash vars in Flash that are only at the root level like the example??

I assume that the ASP page wont like the syntax above as it probably does not understand .syntax?
