RPG question

Ok, here is what I have planned… (Flash 8 AC2)

4 races, 5 characters on each race. Each character is playable, but you must enter a pass at the start, to enable.

How would I do that?
Would each have a variable, like:

race10
race 20
race 30
race 40

And when you start, each character would have like:

If race = race10
Then this = safe

If race = race20
then this = enemy

Or something???

Annnnd… cut scenes… would I put in a new scene? No body has told me how to gotoandstop (scene2) or soemthing? It aint work… it just has errors!! Ahhh!

anyway, any help is much apprecited.
