I'm making a worksheet for my company. I want to subtract one number number from another number. I use the 'sum' format for this '=sum(BL4-BP4) '. This format works fine for me in most cases, if BL4 >BP4. However, if BL4<BP4, the sum that is shown is a negative number. I would like for the worksheet to show only positive numbers. I would like for the cell to show ' 0 ' , or nothing at all, if the sum is a negative number. For instance, 10-8=12 is ok, but 8-10=-2 is not. How do I do this? Thanks
