Here I have list of 4 names in column E along with their associated scored in column F:

Notice also that when there are only two scores, as with Tom, only those two lines of data appear:
The formulas for columns H & I are, respectively:
Note that these are array formulas so they need to be entered with Ctrl + Shift + Enter. The only difference between the two formulas is which column they are pulling the data from, as highlighted.
This is quite a unique process, so take just some time and watch the seven minute video to best understand how the process works.
