Hi, I created a spreadheet that pulls in data from other sheets with Vlookup. I worked with it at home -cut, copied, deleted rows with no problem, saved it, sent it in to the office, I worked with it fine. However, today, as I wanted to edit the spreadsheet in the office, excell started to throw me the "you cannot edit part of an array" message, and wasn't willing to pull in certain data. The Vlookup formula also got enclosed in curly brackets. I came home, opened the same file and the error was gone, it was working like before. It also works on my phone, and on my macbook. What made it stop working on my office computer?
