Sorry, I'm sorta new to excel other than simple data spreadsheets. I know how to simply sum/product multiple cells etc. However, I'm trying to make a product that performs multiple steps that give you a numeric outcome. One of those steps involves a substitution of a number for certain letters that are entered in a cell. Then I need to take the resulting number that is substituted for a letter and involve it in a simple sum with another cell. My question is how to do that? If I try to sum the cell with the substituted number in it it doesn't work because of the formula in the cell.
