Get position uses the position of an object. In this case you want the position of where the player touched, so you use x and y from Started Touching and Stopped Touching
I bought Plastic too and liked their system. Some others I have are below. Ink animator is to expensive to me but appears to be a rising star. I use Pro animation now ($9.99). There is also Doink, but I don't think it has good export features.
