ActionScript 2.0 :: Delay A Function Until Frame Is Reached?

I'll try express this as easily as I can: I have an input text box (call the instance whatever you want). What it does is when you type a word, it makes another movie clip (let's say the instance is MORPH) go to a certain frame. The code is simple, but I'll give it to you to give you a better idea:

[Code].....

check is just a light that turns green if the word is complete, so ignore that. Whenever the MORPH object goes to, say "Earth", it plays an animation and afterwards, it hit's a gotoAndStop(1); code, stopping it at the first frame. What the problem is, say, you type earth, it goes to the EARTH animation, but before the animation finishes and goes back, you type EARTH again and it skips straight to the start of the animation. It looks very rough and bad.

What I want is, say I type Earth and the animation plays, and before it finishes the animation, and I type EARTH again, it waits until morph get's back to frame 1. So yeah, to delay a function until a certain frame is reached. Oh, and another thing. Is there a way to make a button click with AS2? Pretty much when it makes contact with another object, it... clicks (whatever it does to reach the DOWN frame and stay there until the other object moves off).
