Hi
- first select all cells for which you want to ALLOW data entries
- goto 'Format - Cells - Protection' and uncheck 'Locked'
- Protect your worksheet ('Tools - Protection')
You could download the third party tool: AddinTools Assist from http://www.addintools.com. It will temporarily display unlocked cells and
locked cells with different background colors. You will find out which are
locked cells, which are unlocked cells immediately. The "To Lock" button and
"To Unlock" button could lock or unlock the selected cell immediately. In
this way, you can decide fast which part of spreadsheet allows changing, and
which part disallows.
The function is very useful when you have forgotten which cells are locked
in a workbook or sheet.
