Access objects?

this is an object created in main timeline, the problem I have is that this info is stored in memory and read only once it seems. How do I access it from a movieclip and change x and y positions???

Anyone got any ideas

brk1 = {};
brk1.clip = this.brick1;
brk1.x = brick1x;//brk1.clip._x;
brk1.y = brk1.clip._y;
brk1.radius = brk1.clip._width/2;
brk1.mass = 100000000;
brk1.bounce = 10;
brk1.xmov = 0;
brk1.ymov = 0;
trace(brick1x)

Well, _root.brk1.x or _parent.brk1.x should work, no?

It was just me being dumb, changed the wring variable in the function it was passed to!!! Long dayzzz

Cheers
