Problem about _x and _y

Need some help here guys. :be:

I made this movie with a square which follows _xmouse and _ymouse.
I used ‘trace’ to output the corresponding _x and _y of the ‘square’ movieclip.
This works perfectly fine.

However, when I tried to put this ‘square’ MC into another movieclip ‘container’. I could not correctly output the _x and _y of the ‘square’ movieclip. I suppose it is because the trace("_x="+_x) is referring to the _x coordinates of the square INSIDE the ‘container’ MC. How do I output the _x and _y relative to the _root coordinates.

Attached are the 2 fla files for reference.

Thank you for any help :slight_smile:
