Index/Match with Has and Specific Select

Gladys Liley

I have an master roster and each week I need to ensure a response for each. Since each responder has mutliple areas of responsibility, one submission may cover multiple items from the master roster.

I used an index/match formula however when there are multiple entries in a single line, I get a #No Match. And now that the sheet has a secondary week of data, it can't distinguish the difference between last week and this week.

=INDEX({source sheet}, MATCH([ItemA]@row, {source sheet}, 0)

Any guidance is appreciated
