I'm trying to create a spreadsheet that pulls data from another spreadsheet in the same file as well as data from other files. In the attached spreadsheets, I have fields that find the largest value based on dates entered in multiple cells (ie. In my first spreadsheet, I have formulas to find the largest date on that page (=largest(xx:xx), and on my 'master' spreadsheet, I want to find the largest date from the formulas I just mentioned). The problem I'm finding is that excel won't let me include more than two cells in my last formula. It tells me I'm entering too much data. Can someone tell me how to do this?
