I have a spreadsheet with a series of drop down boxes with multiple values.
Is it possible to set up a formula that will add only those cells adjacent to
certain values? As an example, if the drop down has options such as PENDING
and CLOSED but I want to have the system automatically add only the dollar
amounts next to PENDING. Then, when it changes to CLOSED, I would like the
system to automatically re-calculate and shift the specific amount from
PENDING to CLOSED, can that be done? If so, how?

Any assistance will be greatly appreciated. Thanks.
