The sample given would look inside the object called btn for
items named 1, 2, and 3 (asuming modtotal was equal to 3). The two
things wrong with that are there isn't an object called btn and
even if there was you cannot give objects names that are simply
I say "objects" because this array access technique works
with movieclips, buttons, variables, functions, etc. So it is one
of the best tricks in your aresnal.
