Marc's reply is, of course, succinct and correct.
If you want a fuller understanding of scope, I've found the wikipedia article to be relatively clear and to the point: http://en.wikipedia.org/wiki/Scope_(computer_science)
It covers both lexical (a.k.a. "static") scope, and dynamic scope, and gives examples.
