Mixing foursomes

Hi all, This is a list of three golf foursomes over four days. I would like to know how to get the matrix at the bottom to automatically update as I swap the names around. The matrix shows how many times each of two players plays together. I need a formula that counts the number of times any two names appear in any position in the same foursome. Dan

That didn't format well at all! In any case the names are in rows and can appear in any position.
Heres a picture.
