I have been having trouble entering the range. When I browse and add the file I want, the file path is longer than the typing area. If I click on the file path and try to arrow along to the exclamation mark, the range appears midway. However, I finally managed to get the four files up with the range in the correct place and the final total is correct but I am getting peculiar dates, eg 28/12/32 instead of 28/04/16. Any ideas?
