Guessing Game

Hello,

I’m somewhat new to actionscript, I know how to do stuff in flash. Ok, so here’s what I want to know…on this guessing game, I want the person to enter in their 1 - 3 digit guess, the the number they need to guess is 577 (later I want to make this random whenever they go to play it). If they guess under 577, I have a box to say their guess is too low. If they guess over 577, it says their guess is too high. However, I am not sure how to make it so that what they put in the text box, it takes it as the new variable. I know this may sound confusing, but here is the .fla file.
