Please help

I need a way that when I add a person’s name, it appears in front of him the number of times he has been added. That is, if I add two times, the number 2 appears in front of him, or if I add him three times, it appears in front of his name 3

Create a multiple relation that links the name (or ID) to itself. Then create a Rollup column to count the number of rows in the relation. Then use a Template column to join the number and the name together.
