    Welcome aboard!  That's a great bit of code considering the OP offered almost no details.

    It does seem to assume that weeks start on Mondays (which I totally agree with and is ISO).  We'll see how the OP defines what a week is.

    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.
