Look at the hide facility to hide a particular sheet, (Format/Sheet/Hide). Or if you are looking at a tool bar that is on the bottom of the screen, click on the toolbar and uncheck the one that is showing there. With regard to blocking a cell, you will have to go into the Protect system in Excel. Click on Tools then Protection and follow the system through there. Hope this gives you what you are looking for.
Hiding does not work, that totally hides the sheet, I want it accessable via navigation buttons just not the buttons at the bottom of excel. I don't get what you mean Wednesday for what to do there.
What I mean is 1- On the bottom of worksheets it has tabs with sheet1, sheet2, etc... I want these removed however sheets to be accessable via the buttons I have made 2- Make it so you can't click in a cell and write something (though again have stuff added via buttons)
