How to total 12 columns and divide them to get a percentage
I have a table of attendees for a meeting. We track this every month. We have a total of 12 columns, one for each month. When someone attends I enter a 1 beside their name. If they don't attend they receive a 0. On the far right in the last column I want to be able to total the columns and divide them by 12 to find out the percentage of their attendance for the year. TIA
