Thank you for you help! I am going to sound like a completely incompetent but I cannot open your file correctly. When I do it asks about enabling macros, which I do, then it says its unreadable and to "open and repair", then asks me two more times about enabling macros then to save the log book? Once the document is open the values are in the summary sheet but no formulas. Any ideas as to what I am doing wrong? Thank you again!
