Assume a two column database with names in column A and numbers in column B. Names in column A may be repeated. If a user types a certain name in a cell, a formula should sum the highest three values from column B for that name.

Depending upon the version of MS Excel which you are using, there could be two ways to solve this problem

**Solution for MS Excel 2010 and higher versions**

If you are using the PowerPivot add-in, then a simple DAX formula can solve this problem.

**Solution for all versions of MS Excel**

While this solution works for all versions of MS Excel, it uses an array formula (Ctrl+Shift+Enter). Array formulas, if used extensively in the workbook, adversely effect the system's performance.
