alpha value doesn't change in roll_out event flash cs5

Question

I am newbbie in Flash CS5 and AS3 and I have a problem! I have 3 rectangles on stage converted in MovieClips with given instance names. All three have the property of color effect: alpha = 50. I have type the following code in as3 layer :

addEventListener(MouseEvent.ROLL_OVER, RollOverBtn);
addEventListener(MouseEvent.ROLL_OUT, RollOutBtn);

function RollOverBtn(event:MouseEvent):void
{
    event.target.alpha = 100;
}

function RollOutBtn(event:MouseEvent):void
{
    event.target.alpha = 50;
}

The problem is that when the mouse rolls over one rect, alpha changes to 100. But when the mouse rolls out, nothing happens!

Any suggestions?

I have changed my code to :

btn1.addEventListener(MouseEvent.ROLL_OVER, MouseOverBtn);
btn1.addEventListener(MouseEvent.ROLL_OUT, MouseOutBtn);

btn2.addEventListener(MouseEvent.ROLL_OVER, MouseOverBtn);
btn2.addEventListener(MouseEvent.ROLL_OUT, MouseOutBtn);

btn3.addEventListener(MouseEvent.ROLL_OVER, MouseOverBtn);
btn3.addEventListener(MouseEvent.ROLL_OUT, MouseOutBtn);

function MouseOverBtn(event:MouseEvent):void
{
    trace("roll over"+event.target);
    event.target.alpha = 1;
}

function MouseOutBtn(event:MouseEvent):void
{
    trace("roll out"+event.target);
    if(event.target.alpha == 100){
        event.target.alpha = 0.5;
    }
}

and the trace message I get is :

roll over[object MovieClip]
roll out[object MovieClip]

This, as I can understand means that the roll_out is triggered but still not changing alpha property.

Alpha can have a values in range 0-1, not 0-100.
Where did you attach listeners? They should be added to buttons.
