Hello, if I have in cell C a price which is made up of 3 values: D, F, H,
but
not in all cases all of these apply. So on cell E, G, and I would like to
have a "x", that if I do have it then it sums the value to the left to the
value to cell C, If i have all 3 with x's, it sums all, and so on... How
can
I manage that?

thanks in advance!
