I have a customer name (Tina) and numbers that go with Tina's information
(575, 125, and 700). How can I find the highest number, and delete the other
numbers as well? I want to find her highest score, and keep it, and then
remove any other numbers.

I tried putting a table in, and then filtering, and finding the highest
number (MAX function) but I still have all her other numbers.
