Move an animator object from right to left

[cgele]

How do I move an animator object from right to left?  I tried using the value with a minus sign in front of it. (i.e. -(xcoord) )  Please help.

Thanks,

Chris

After you create the animator, click on it on the panel, you will see a rectangle. You can drag the rectangle to bigger or smaller. The graphic will be moving inside of this rectangle. In this rectangle, bottom left corner is x0 y0.  Top right cornet is x100, y100.
