I have a file that I want to enter 13 weeks of data for 100 rows and 5 columns. On the 14th page, I set up 2 list boxes with the first 13 page names as options. I want to be able to pick 2 page names from those boxes and use those in a claculation that will average data in a specific cell from choice page 1 to choice page 2. Is this possible?
