I have a excel document that has all the ores, logs, food,bows,bow(U),bars, and other items that go with smithing, cooking, fleching and crafting that can be sold in the GE I also have in there the formula that will add up how much u need to spend, how much u will gain and how much profit there is by doing it. the cells that are blank are the prices for each item and once they are filled in all the numbers will show up but then if a price goes from say 300 to 350 then I need it to update automatic.
