Hi, I am in the first day of term where you have to go get the glacius spellbook. i have entered into a room where there are three panels on the floor that need to be pushed in order to reach a button on the top level. I have the button revealed by having Hermoine and Ron stand on the panels and the trunk on the 3rd. I have gotten Harry on top of the bookcases but he falls whenever i try to make him jump from bookcase to bookcase. i have no idea what else to do or what i am doing wrong. Any suggestions would be much appreciated, thank you!!!!
