That's a good question. I'm trying to figure that out myself. I've looked thru all the menu choices - File, Home, Insert, Page Layout, Formulas, Data, Review, View, and PDF but can't find any reference to zero values or any box to check for it. In previous versions it was easy - it was under tools, but there is no tool menu in 2010. I must have a different version than the answer above because I don't have an Excel Options menu choice. Any help on this would be appreciated. Thank you.
