How do I built a conditional Vlookup?
For example, if source cell = X, then use =VLOOKUP(F1,A1:B2000,2,FALSE)
... where I look-up values from the 2nd column from the lookup range.
However, if source cell = Y, the use =VLOOKUP(F1,A1:B2000,3,FALSE)
... where I now want to look-up values from the 3rd column
