How do you beat level 125 in cover orange

You use the first wheel and drop it on top of the bomb next to the short, brown plank of wood, setting it off and causing the wood to shoot over to the other side. then with the second wheel, you drop it ontop of the bomb next to the long, golden plank of wood (not the bomb onto of the wood!) and it will set the bomb off, moving the wood and dropping the bomb in between the last two remaining bombs. they will be triggered, shooting the short, brown plan of wood over and knocking the orange to safety.
