Batmap data

Hi everyone. I’m using some code I picked up in one of the discussions and I’ve got a strange problem. The code works fine on its own but when I add additional layers there is a problem.

The class or interface ‘BitmapData’ could not be loaded.
var bitmap:BitmapData = new BitmapData(mc._width, mc._height, true);

Maybe some of the code is conflicting - I’m not really sure. Can anyone help?
