Lookup based on certain condition

Hi all

Wondering if it's possible for vlookup or index/match feature to include logic so it selects an answer based on "last active cell".

For example, I have a list of employees and the "# of calls" they make. One individual is listed 3 times b/c they changed groups. The data shows the # of calls by months from July 2015-May 2018. When I do a vlookup or index/match, it returns the first value it finds....value I want to find is what "group" they work for, which is listed in column "B" in the productivity tab

Is there any way to add logic in there where it scams through columns "H:AS" in the "productivity" tab and sees, for i.e. "Doe, John", which row of the 3 groups, has the most active data. For example, "Doe, John, is listed in productivity tab, in row 11:13. Row 13 shows the most active data, as row 11 and row 13 show 0 for month of may.

I want my vlookup or index/match in the Lookup to show "intellectual property & tech" as the answer ; my current formula shows "employement labor".

can someone pls help?! I have attached a sample sheet.
