AAARRGGGHHH whats wrong?

I’m trying to make an AI, but its not working well.
its supposed to have a turn where it attempts to play the game.
heres the code for the frame:

//Function Block
wait = function (displayTime) {
    timer = setInterval(wait, 1000);
    displayTime--;
    if (displayTime == 0) {
        clearInterval(timer);
        return 1;
    }
};
contains = function (input, arrayData) {
    for (i=0; i<arrayData.length; i++) {
        if (arrayData* == input) {
            return 1;
        }
    }
    return -1;
};
index = function (input, arrayData) {
    for (n=0; n<arrayData.length; n++) {
        if (arrayData[n] == input) {
            return n;
        }
    }
};
//Setup Block
score;
compscore;
_root.Match = "none";
_root.LastMatch = "none";
turn = "player";
Stage.showMenu = false;
CardBlue1.useHandCursor = false;
CardBlue2.useHandCursor = false;
CardRed1.useHandCursor = false;
CardRed2.useHandCursor = false;
CardGreen1.useHandCursor = false;
CardGreen2.useHandCursor = false;
CardYellow1.useHandCursor = false;
CardYellow2.useHandCursor = false;
//Shuffle Block
Card = new Array(_root.CardBlue1, _root.CardBlue2, _root.CardRed1, _root.CardRed2, _root.CardGreen1, _root.CardGreen2, _root.CardYellow1, _root.CardYellow2);
shuffle = random(7);
Card[shuffle]._x = 120;
Card[shuffle]._y = 130;
Card.push(Card[shuffle]);
Card.splice(shuffle, 1);
shuffle = random(6);
Card[shuffle]._x = 320;
Card[shuffle]._y = 130;
Card.push(Card[shuffle]);
Card.splice(shuffle, 1);
shuffle = random(5);
Card[shuffle]._x = 520;
Card[shuffle]._y = 130;
Card.push(Card[shuffle]);
Card.splice(shuffle, 1);
shuffle = random(4);
Card[shuffle]._x = 720;
Card[shuffle]._y = 130;
Card.push(Card[shuffle]);
Card.splice(shuffle, 1);
shuffle = random(3);
Card[shuffle]._x = 120;
Card[shuffle]._y = 340;
Card.push(Card[shuffle]);
Card.splice(shuffle, 1);
shuffle = random(2);
Card[shuffle]._x = 320;
Card[shuffle]._y = 340;
Card.push(Card[shuffle]);
Card.splice(shuffle, 1);
shuffle = random(1);
Card[shuffle]._x = 520;
Card[shuffle]._y = 340;
Card.push(Card[shuffle]);
Card.splice(shuffle, 1);
shuffle = random(0);
Card[shuffle]._x = 720;
Card[shuffle]._y = 340;
Card.push(Card[shuffle]);
Card.splice(shuffle, 1);
//AI Block
Memory = ["none"];
if (turn == "computer") {
    pick = random(7);
    if (Card[pick].matched != true) {
        Card[pick].gotoAndStop(2);
        _root.Match = Card[pick].colour;
        _root.LastMatch = Card[pick];
        if (wait(1) == 1)
        if (contains(Card[pick].matchy, Memory) == 1) {
            chance = random(100);
            if (chance<((100-10)-index(Card[pick].matchy, Memory))) {
                Card[pick].matched = true;
                Card[pick].matchy.matched = true;
                Card[pick].gotoAndPlay(3);
                Card[pick].matchy.gotoAndPlay(3);
                compscore += 1;
            } else {
                picky = Card[random(7)];
                if (picky.matched != true) {
                    if (Card[pick].matchy == picky) {
                        Card[pick].matched = true;
                        Card[pick].matchy.matched = true;
                        Card[pick].gotoAndPlay(3);
                        Card[pick].matchy.gotoAndPlay(3);
                        compscore += 1;
                    } else {
                        Card[pick].gotoAndPlay(8);
                        picky.gotoAndPlay(8);
                        turn = "player";
                    }
                }
            }
        }
    }
}
//Player Turn Block
Playercardnumber = 7;
if (turn == "player") {
    while (Playercardnumber>=0) {
        if (Card[Playercardnumber].matched == false) {
            Card[Playercardnumber] = enabled;
            Playercardnumber -= 1;
        } else {
            Playercardnumber -= 1;
        }
    }
}

and for the cards:

onClipEvent (load) {
    stop();
    var colour = "green";
    var matchy = _root.CardGreen2;
    var matched = false;
}
on (release) {
    Memory.splice(index(this, Memory), 1);
    Memory.unshift(_root.CardGreen1);
    if (_root.Match == "Green") {
        this.gotoAndPlay(3);
        _root.CardGreen2.gotoAndPlay(3);
        _root.Match = "none";
        _root.Score += 1;
        this.enabled = false;
        this.matched = true;
        _root.CardGreen2.enabled = false;
        _root.CardGreen2.matched = true;
    } else {
        if (_root.Match != "none") {
            gotoAndPlay(8);
            _root.LastMatch.gotoAndPlay(8);
            _root.Match = "none";
            this.enabled = true;
            _root.LastMatch.enabled = true;
            _root.LastMatch = "none";
            turn = "computer";
        } else {
            gotoAndStop(2);
            _root.Match = "Green";
            _root.LastMatch = this;
            this.enabled = false;
        }
    }
}

I think this is in AS 2, but it could be 1
