buttonLoopScript problem

programming flash
1

Attached is my .fla file for flash cs3. What I want to happen is for the first button to automatically become activated and play the PageIn0 clip upon playing. Can anyone help me out? Thanks!

CODE:

currentButton = null;
firstButtonPress = true;

function buttonCheck(n) {
buttonCollection[‘b’+n].onRollOver = function() {
this.gotoAndPlay(‘in’);
};
buttonCollection[‘b’+n].onRollOut = function() {
this.gotoAndPlay(‘out’);
};
buttonCollection[‘b’+n].onPress = function() {
this.gotoAndPlay(‘press’);
this.enabled = false;
buttonPressed(n);
};
}

function buttonPressed(n) {
if (firstButtonPress == true) {
mainClip.gotoAndPlay(“pageIn”+n);
firstButtonPress = false;
} else {
buttonCollection[‘b’+currentButton].gotoAndPlay(‘out’);
buttonCollection[‘b’+currentButton].enabled = true;
mainClip.gotoAndPlay(“pageOut”+currentButton);
}
currentButton = n;
trace("you pressed button "+n);
}

for (z=0; z<5; z++) {
buttonCheck(z);
}
