I just don't get it.

I have this preloader where I get % loaded (start: 0 completed: 100%)
Now I need to move a movieclip _x cordinate from _x 65 to 200

How can I move the clip based on percent loaded?
eg.
start: 0% mc._x = 65
end: 100% mc._x = 200

can anyone please help me out

thanks in advance,
best regards T
