"big" has no height property.. what is the type of the "big" object?

[chocolate1146]

Look like you try to work with microphone amplitude, show microphone data gain to bar. Maybe "big" is a display object like sprite. Try use graphics might help:

big.graphics.clear();

big.graphics.beginFill(0x00FF00);

big.graphics.drawRect(0, 0, _width, _sx);

big.graphics.endFill();
