Easy Question - updating AS 1 to AS 2

I am new to actionscript and I have a piece of code that I need to update to as2. It is for a menu that scrolls a movie clip horizontally. I am sure this is easy, but I just don’t have a handle on the syntax.

Here it is:

startx = getProperty(/:info,_x);
moved = /:targetx-startx;
setProperty(/:info, _x, startx+(moved/7));

Thanks in advance.
