right-click on the cell(s) highlighted and select "format cells" and the "protection" tab and tick the "hidden" box. select OK. The sheet (and cells you chose as hidden) are still viewable until you select from the toolbar "Tools", "protection", "protect worksheet" - at which point you can set a password. Now the cell formula is hidden! - you can disable protection through tools, protection, un-protect worksheet (and entering the password). PS welcome from Darth also......
