I'm using Excel 2010, and have a spreadsheet of simple numbers (they're 1-5 ratings for a range of questions), so I have questions across the top, and each person's responses as a separate row.

5,2
6,5
7,5

What I want to know is which numbers are missing from 1 to 13 (in this case 13 is last number in column 1).
