Daryl,

The basic problem is that Frame is designed to work with a multi-file model that uses book files to hold multiple "document" files.

You're trying to acccess variable and tag information from the component files at the higher book level, and it isn't working because the level of communication that you're looking for doesn't exist. The solution that most people use is to define user variables in a component file or a template and then share those among all component files.

As Nils suggests, the easiest way to do what you want is to replace the default configuration Building Block that you're using with a file-level user variable that's the same in all component files. Shlomo's suggestion to set the <$volnum> variable at the book level will also work, but most users use the first solution.
