ActionScript 3.0 :: Create An Instance At The Correct Position?

basically, I am trying to create an instance at the correct position. I understand that I will have to utilize globalToLocal() and/or localToGlobal() to get relevant positions, but for some reason, I can't position the instance at the correct location. here is the codes:

parent class:

Code:
//create bullet
bulletList.push(new Bullet(100, 100));
addChild(bulletList[bulletList.length - 1]);
Bullet class:

Code:
x = localToGlobal(new Point(pX, pY)).x;
y = localToGlobal(new Point(pX, pY)).y;

pX and pY are the arguments for the Bullet Class. When I do this, it is shifted over 100, so the absolute position being x = 200, y = 200, and the local position being x = 100, y = 100.
