Pong Game Help

I am using the pong game tutorial, with all of the actionscript and it is all working except i have one problem I am making it a different size…I want it to fit in a 120x600 area and the ball and bar and game arena are all fitting in there, however, when I put the bricks in there they line up to the old arena. So basically about half of the bricks fit into the playing area and half of them don’t, the bricks are also too big…Does anyone know how to make all of the bricks fit in the area of 120x600? I appreciate the help. Thanks.
