I finally figured it out but its kinda hard to explain and probably not how it was suppossed to be done. i connected the battery to the gear thing. i put 1 gear on the bottom gear and connected that to the other open one with the belt. then i turned the weight on its side, hook facing left, and placed it on the end of the middle board. then i placed the other gear above that to help make the box go where it is supposed to. i hope that helps if ur still stuck let me know and i'll try to make it a little clearer
