So the script is suppose to make the pixel see though when i click on it… why doesnt it?

```auto
import flash.display.BitmapData;

var guiBitmapData:BitmapData = new BitmapData(200, 200, true, 0xFFFFFFFF);
var gui:MovieClip = this.createEmptyMovieClip("gui", this.getNextHighestDepth());
gui.attachBitmap(guiBitmapData, this.getNextHighestDepth());

function d(x, y, color) {
    guiBitmapData.setPixel(x, y, color);
}
gui.onPress = function(){
    d(_xmouse,_ymouse,0x00FFFFFF);
}

```

Thanks.

//edit,  
This is where it told me that 0x00FFFFFF was transparency…

What you want to do is use setPixel32 instead of setPixel.

Hope that helps.
