i see that the Wood Drawer Box subassembly has a variable called File_Drawer, that toggles when you set the various File Drawer toggles...what i don't see....is HOW it does that.

Because the template value for File_Drawer is =0

But somehow when i switch to File Drawer in the product its becoming a hard coded 1.

This isnt a problem...but just by my understanding about how the spreadsheets and subassemblies and products work...its impossible.  So there must be some functionality i don't know about here.  Any ideas?
