Propagating the values should not be a problem. The question is how. What
is 'B', what is 'C'?

On in include, you won't have to worry about this, it will be automatically
available. On a different request (page change), you'll have to propagate
the value by either a session, or a POST or GET variable.

Be warned to never trust POST or GET variables before extensive validation.
