Answer 1

Its usually best in cases like this to work within the Excel paradigm rather than convert to the C# way: Not sure why you need a UDF rather than the Excel formulae which your Finance guy has coded: why can't you/finance guy just code some fomulae to feed the inputs to the finance guy sheets, then write some more formulae to feed the results back? If you really need to do this with VBA then J Tolle has given you the basic architecture for a repetitive loop but I would recommend looking at doing it with formulae first.
