Problem with arrays!

1

I’m trying to make a little hangman game but I’ve run into a few problems…I’m hoping that maybe someone can give me an idea what to do.

I’ve had some help with the code below but that just left me even more confused!

I’m basically trying to give users a small clue as to what word it might be they have to guess.

stop();
_global.adPairs = [
['PC', 'Personal Computer'],
['AS', 'ActionScript'],
['RAM', 'Random Access Memory'], ['WWW', 'World Wide Web']
]; // etc.

initGame();
stop();
function initGame(Void): String {
		// get phrase
		var rPair:Array = adPairs[Math.round(Math.random()*(adPairs.length-1))];
		man.gotoAndStop(1);
		// build display
		display = "";
		for(var i:Number = 0; i < rPair[1].length; i++) {
				// place characters
			    display += (rPair[1].charAt(i) == ' ') ? ' ' : '_';
		}
function makeGuess(code) {
	// get the character that links to the key pressed
	letter = String.fromCharCode(code);

	// check to see whether it is a letter
	if (isAlpha(letter)) {

		// assume that the letter won't be found
		gotOne = false;

		// start building new display
		newDisplay = "";
		for(i=0;i<phrase.length;i++) {

			// see whether letters match
			if (phrase.charAt(i).toUpperCase() == letter.toUpperCase()) {

				// place letter in display text
				newDisplay = newDisplay + letter.toUpperCase();

				// note that at least one match has been found
				gotOne = true;

			} else {

				// not found, so display same character
				newDisplay = newDisplay + display.charAt(i) ;
			}
		}

		// show new display
		display = newDisplay;

		// if no match found, then add more to man
		if (!gotOne) {
			man.nextFrame();

			// see whether the man is done
			if (fox._currentFrame == 8) {
				gotoAndPlay("lose");
			}

		} else if (display == phrase.toUpperCase()) {
			// the display matches the original, game over
			gotoAndPlay("win");
		}
	}
}
	
// utility to test whether a character is in A-Z
function isAlpha(letter) {
	// get character code
	n = letter.charCodeAt(0);

	// convert low case to upper case
	if (n > 90) n -= 32;

	// see whether it is in A-Z
	return ((n >= 65) and (n <= 90));
}

If you know what to do I’d really appreciate it!
