    I work with serialized parts. When something goes wrong with a group of parts, I must list all the affected serial numbers. There are several different things that can go wrong so in a single sheet, I list the problem and then the affected serial numbers.

    I need to be able to look across the entire population of data and retrieve a count of the number of unique serial numbers.

    Spread sheet attached.

    Any help that can be provided would be greatly appreciated.

    As an addendum to this post, if the result could also include a number of instances a given SN is present in the array that would also be beneficial.
