I am trying to get a formula for excel

I have
merchandis Amount
shirt 13 29.95
pants 22
shoes18
dress16

We may be able to help but you need to tell us what you are trying to do. Regarding your post, is that 13 shirts @ $22.95 each or 13 shirts at a total of $22.95. Also, you have no heading for the 13. Does amount refer to the number of shirts or to the cost.
