Flash Multi Touch help

I am creating a Multi Touch game for a project of mine. I have created the desktop versionusing actionscript 3 and mouse clicks, but I need to convert it into multi touch. Below you will see the code for one of the levels.

Aims: The main game is a sniper based, you will have a completly blacked out screen with a cross hair only showing you a certain amount of the screen.

Solved problem: I have been able to convert my enemies to multi touch pretty easily with the touch begin events etc so they are not a problem

UnSolved problem: The code at the bottom in red is my issue, the creation of a pure black screen is fine I have that but to enable multi touch instead of a mouse is a little tricker. I can kill the enemy as I said above but I can't seem to get the correct command in to drag the "scope" around the screen.

IF anybody knows the code to put in it would be greatly appreciated or knows a tutorial that could help me out.

Thanks in advance,

Jason
