    This works perfectly, thanks, but what can I do in case of dependant lists, where the secondary list depends on a primary list in another cell?

    I recreated the exact same formulas and cells and it repeats the numbers. Instead of 1, 2, 3, it's showing, 1, 1, 2, 2, 3, 3, etc.

    I'm just getting circular reference on the max formula? It's not working. If I change my iteration settings, it just keeps continuously keeps adding for no reason.

    Thanks. For some reason i does not populate the last 8 row. Say my total count or max value is 34 this formula populates only 26. Any idea?
