In creating a financial analysis spreadsheet, I grouped the Income Statement, Assumptions, and Analysis each into its own group. On the left side, I have the + sign and at the top of the column I have the 1 and 2 buttons. In the development of the spreadsheet, the + sign and - sign were working to collapse and uncollapse the groupings as were the 1 and 2 buttons. Now, neither the + sign, -sign, or 1 or 2 buttons work. The groups are currently collapsed. How do I get them to uncollapsed? The cells are not locked. Any assistance would be greatly appreciated. Thank you!
