Solution 22111: Lists and Spreadsheets on the TI-Nspire™ Family Products Will Not Allow Selection of Another Cell or Resize of a Column After Error Messages.
Why does the Lists and Spreadsheets application on the TI-Nspire family prevent the selection of another cell or resize of a column after error messages?
If an invalid formula is entered into a cell, Lists and Spreadsheets application will not allow the selection of another cell or the resizing of a column until the invalid formula is cleared or corrected. Once the invalid formula is cleared or corrected, the error messages will stop and other actions will be permitted.
For more information on how to use the TI-Nspire family products please refer to the TI-Nspire family guidebooks.
