Ok, those boxes are for picking up specific things. Let's say you have your item box full of potions, and if you have it pick up all, it will eventually drop the potions to pick things up. So if you only want it to pick up certain things like, just gold or just necklaces or just earrings, when you click in the circle (near the a and b) a pop up should come up and read it. It will tell you what number to put in the B box to pick up certain items. Type in the A box the name of something you want it to specifically pick up. Hope that helps
