How do I create the formula I need? Dummy version

William Young

I used the formula =sum(qty1 * cost1) to get my total cost. I copied that formula down my total cost column and have a bunch of blank rows showing $0.00. How do I adjust my formula to leave empty rows blank?

Try the following, which looks to see if Quantity is either blank or equal to 0, if so, then the result will be blank, otherwise it will multiple the valid quantity entry by it's unit cost.

=IF(OR(ISBLANK(Qty1), (Qty1 = 0)), "", (Qty1 * Cost1))
