Counting Combinations across multiple columns
I've got a group of data (about 200 rows long) with the following headers:
Student Name Grade Level 1st Choice 2nd Choice 3rd Choice 4th Choice
The four columns for 1st through 4th choices will contain information as students select between 6-8 course offerings and they will choose four of them ranked 1 through 4. I order to schedule the courses (as only 2 of them will be scheduled at any one period
in the day) I need to determine which 2-course combinations occur most offen. So, with 6 courses (here I'll call them C1, C2, C3, C4, C5, and C6), I would need to check which of the 15 combinations (6*5/2...C1/C2 is the same as C2/C1) occurs the most often.
My preference would be to do this through a forumla so that the counts update as the information is updated. Doing it through a macro would be fairly straight forward but I'm not sure how to even start with a formula for cells to do this. Any help would
