Ina wants to protect a worksheet with a password, but still provide a data entry area where users can change data.Before protecting the worksheet, she should unlock the cells she wants to allow users to edit.

To allow users to change data in specific cells, those cells must be unlocked before protecting the worksheet with a password. This can be done by selecting the cells, going to the "Format Cells" option, and then unchecking the "Locked" checkbox. After that, the worksheet can be protected with a password to prevent users from making changes to other cells other than the ones that have been unlocked.
