HARRY POTTER YEARS 1-4

Yesterday I got a Harry potter years 1-4 wii game.I use it with my money it was $44 I had $24 so mum let me miss out of pocket money for a month because 24 +20 =44 beoucas I get $10 each two weeks.I'm stuck on a bit where you have to stop Snape from getting harry of his broom stick because it's a flying one he could fall off.At the start you don't have a wand because you haven't been to green gots bank and get your money then you open some things then you walk around and look for a arrow and go in the shop next it's an add.it's an  awesome game!
