Need some attacking help!

I have a movieclip with 3 frames in it. 1=standing 2=running 3=attacking
I am trying to figure out how it is so when the attack animation hits the enemy, the enemy plays its second frame, which is it dying. Attacker= instance name: man2
Enemy= instance name: enemy

Plz! I really need this help! Thanks! (that is if you help)
