VLOOKUP Across Several Worksheets (2) – Multiple Search Criteria 9

I recently made the post here, in which I presented a solution to the problem of returning a value based upon matching a single criterion in a given column across multiple worksheets.

In this follow-up post I will look at the analogous case in which we are not matching a single criterion, but several. As mentioned in the first instalment, I will look at two solutions to this problem, one in which we make use of an extra “helper” column in each of the relevant worksheets, and one in which we do without such aids.
