At this point in OP's learning curve, we are light years away from
teaching best practices. He asked how he could access a local variable
in a function from an included script file. Suggesting a global variable
at this point is, in my personal opinion, the right thing to do. It
teaches about scope. Judging from the follow-up, even that presented
some problem, which has yet to be solved. Your suggestion about the "one
global variable" is correct, but ten steps ahead of where his current
priorities lie (i.e., "how do I get this to work" rather than "what's
the best way to design this"). For this reason, I reject your critizism
of my "bad advice". Both of us have decades of experience with
JavaScript, but apparently only one of us has any experience with teaching.
