My thinking is that it is not returning a value for the other rows as the Buyer Cost of 1 is not in this data. I was hoping the formula would calculate the bottom half of it independently but it appears this is not the case.
I can calculate this easily in excel but my thinking was that in Qlik Sense would be easier to switch the data between different buyers using filters. We have a lot of buyers and In Excel we have to keep reloading data for each one
Hope this makes sense and any help you can give would be greatly appreciated.
