I have a number that needs to be decreased based off a % improvement matrix located in my excel file. I'd like this number to be decreased by a user select denotation (ie "x") next to the corresponding improvement parameter. Is there a function that will sum the percent improvements if a user selects multiple improvements? For example, if the number is 100 and a user chooses 2 25% improvements, this result in 50, it would result in approx. 57.
Thanks!
