RE: Protection
Hello Efua
Thank you for your question and welcome to the forum.
To apply protection to a worksheet, go to the Review tab, and click the Protect Sheet button.
Create a password (if you wish), and tick any actions that you want people to be able to perform even when protection is applied.
If you have entered a password, you will be prompted to enter it again.
Click OK to apply protection.
Kind regards
Amanda
