The above logic is from edingtoncollection and tells the system to ignore the sales price when logged in. I am trying to do the opposite. I want it to ignore the sales price when NOT logged in and to apply the sales price when logged in. I am still struggling to make this happen. I thought it would have been as simple as changing != '0' to ='0' but that did not work. Can someone offer some assitance?
