Hi,
This is clearly a much simplified example and probably doesn't represent the size of your actual data. We often find that when we give an answer to what is a trivial non representative example when the solution is used with the real world data it doesn't work because of factors like string length and other stuff which is important but hasn't been mentioned.
Therefore upload your real workbook (or at least a cut down copy), and manually add the results you expect to see. Clearly identify which is original data and which are the results and in a note clearly explain how you have arrived at your results.
That said and assuming the years are always sorted as you show then in D1 copied down
Otherwise upload the workbook.
