RPG game logic help!

Good day,

Im working on a RPG turn based game(classical) in flash as3 using flash cs5.5
and i got some errors on battle system…

i wish that u could help me with my problems. thanks a lot in advance.

Problem :

Turn Based battle system

(i got some errors here)

adding more enemies on the stage.

my enemy is not actually random but i rather placed it directly on the stage and when I touch it and press space key will proceed to battle frame. now i got some weird error on this.(but no error if i removed the second enemy). please hope you guys help me with this thing. i search the net and i got nothing, so please even a hint on the problem willl be much appreciated. thanks in advance.

cheers,
raphaelle
