Type in the answers and the more block will make it go up and then down. A few things: 1. If the speed is Zero, it will not do anything. 2. If the speed is below Zero, it will go down forever. 3. If the how much up is not a number, it will go up forever. 4. If the speed is not a number, it will not do anything. 5. If the how much up is zero or below zero, it will not do anything. 6. If the how much up is not divisible by the speed without being a decimal, the sprite might go too high up or too low down or both.
