MATCH with two columns: nested?

Hi All,

I'm an excel noobie and in my opinion my first excel task seems pretty complicated. So here it goes.

I have two columns of data. Timestamp and TagNames. Both have duplicate entries. There is a third column, Value.

For each timestamp & tagname combination, there is a unique value.

I want to be able to create a conditional search statement which takes Timestamp and TagName as input and gives me the Value that matches both conditions.

I would immensely, greatly and all synonyms thereof appreciate your help!!!

Thanks!
