adding a new set of animation frames?

I did the first animation thing. I made a function called player_shot_throw. Then I put     

 self.weaponframe += 1;   
if (self.weaponframe >= 62)
{
pull finished();   
return;
}   
superdamagesound();   
 self.attack_finished = time + 0.2);     
self.impulse = MSG_BROADCAST; 
}; 

That is my code. I also put

startwframe (self, 51); 

 So if I want this animation to be played every time I switch weapons, where would I put it?  Would I put it in cycleweaponcommand? How do I actually view this animation in game?
