GUI - refresh problem

Question

I wrote a new code which draw two shape; circle and rectangle. I aim to cotrol their places with sliders. However, There is a problem about that. When I use slider, a new slider occurs in the panel. And when I move shapes, previous actions don't disappear except when playing the window. When you run it, you can see.. [http://www.shnkc.tk/shape-luck ] This is the link of it. If you mail your correct answer to me I will appreciate it. Thanks. <[email protected]>
