Margin when only have employment numbers?

Hi Ben. Thank you for your post. Yes this should be and the Software is doing exactly what it is suppose to do. When the Industry Sales value is entered the Software assumes this is in Purchaser prices. The Software then converts this into Producer Prices by margining. However when any of the other three Input fields (Employment, Proprietor Income, Employee Compensation) are used the entered value is by definition already a Producer value. These values are already margined, in effect, because you are looking only at the retailers operational costs equivalent to Gross Retail Margin.
