• Sorry Alex,

    I just didn't have the time to warp the data into a table.

    Dwain's solution is pretty much the same (just missing pre-aggregation but not a big thing) as what I was going to demonstrate so you're good to go there. The question is, do you understand the code and why it works?

    RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
    First step towards the paradigm shift of writing Set Based code:
    ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

    Change is inevitable... Change for the better is not.
