There's a problem with this code. FIRST: Debug so that when you click on a fraction, it goes to the base of the correct pillar to show the shaded portion (darker). THEN: you'll need to debug the comparison symbols to show how the shaded portions compare.
Remember: You must first drag the fraction bucket to the bottom of the pillar it can paint. THEN, you grab a "Glide to x,y" block and click it into the "When this sprite clicked" code.
