if anyones good at turing, perhaps you can help me. you see, i created an average finder in turing to find the average of two imputed numbers by the user, and also added a small button in the corner that the user can click to exit, that being said, i've modified it so that it changes color when the mouse moves on to the "button" (drawfilloval) by overlapping it with another button any time the mouse is in that area, however, it seems that will not work correctly, as it makes it give strange colors, a hybrid of the two if you will (the two colors overlapping eachother). im at a loss at how to fix this issue, i shall post the full program in its .t format here:
