Hi this is my first post so it would be great if someone could help.

i am trying to assign boolean variables to my script that i have made, basically i have never done it before so i have no idea how to add them to my script. i am controlling movieclips using alpha levels so when a key is pressed it makes a mc =100 and when the key is released it takes the alpha back down to 0. My mc work fine along with the keypresses, its just i need more control over what has already come up.

I want to use the boolean variables so that they control the mc and stop them from playing after a certain amount of times the key is pressed.  
here is some of my script:

stop();  
this.onEnterFrame = function() {  
if (Key.isDown(65)) {  
trace(“It’s an A”);  
girl\_mc.\_alpha = 100;  
} else {  
girl\_mc.\_alpha = 0;  
}  
if ((Key.isDown(85)) && (Key.isDown(65))) {  
trace(“It’s a U and an A”);  
carnival2\_mc.\_alpha = 100;  
} else {  
// if it’s not down  
carnival2\_mc.\_alpha = 0;  
}  
if ((Key.isDown(85)) && (Key.isDown(65)) && (Key.isDown(84))) {  
trace(“It’s a U, T and an A”);  
tree\_mc.\_alpha=50, carnival2\_mc.\_alpha=0, yo\_mc.\_alpha=50;  
} else {  
// if it’s not down  
tree\_mc.\_alpha=0, yo\_mc.\_alpha=0;  
}  
if ((Key.isDown(85)) && (Key.isDown(65)) && (Key.isDown(84)) && (Key.isDown(79))) {  
trace(“It’s a U, O, T and an A”);  
handy\_mc.\_alpha=50, carnival2\_mc.\_alpha=0, tree\_mc.\_alpha=0, yo\_mc.\_alpha=0;  
} else {  
// if it’s not down  
handy\_mc.\_alpha = 0;  
}  
};
