VBA help

Sorry for the title, couldn't think of a short yet more descriptive one

Hello, it's one of those days where it's 1am and I'm trying to accomplish something, yet failing miserably. Trying out functions, but obviously I can't pass value to Excel. Yet, couldn't figure out which cell the Sub should take it's values from. What I'm trying to do is for Excel to look at last row or any row for that matter. Not sure if I should put it into the SheetCalculate or SelectionChange or something..

I've a sheet where at column CB, CC, CD (user input fields) has different integer values for scenarios in each row. I'm trying to tabulate different values for these 3 inputs.
Ex: function calculate (CB10, CC10, CD10) (user input field) => calculate ($1, $2, $3)

These are to be fed into the T20, U20, V20 where Excel built-in functions will work it's magic to throw out results in AK60, AL60, where I'd like to show up at CE, CF...
Ex: T20, U20, V20 = CB10, CC10, CD10 = $1, $2, $3

After the scenario, AK60, AL60 = $156, $2000 => CE, CF = $156, $2000

I can't possibly put the calculations in the sheet into VBA. (A1 thru CA60)

Hope this makes sense, otherwise I'll have to cleanup the Excel and attach..

TIA!
