I think the "2" needs to be 2F. I don't have the code infront of me right now, but check if there is a float needed. I know it needs a name, a mining lvl, max uses, but i'm unsure about the rest. If it days (float) there needs to be an F at the end of the number, if it says int, it's just the number. If it says boolean, its true or false. Any other problems, i'd be glad to help tomorrow
