Hello Robert,
All cells are locked by default but it is not turned on unless yo
protect the sheet.
If you only want certain cells to be locked you will need to unlock al
cells, lock specific cells and then protect the entire sheet:
Highlight all cells (click the grey box to the left of A and top of 1)
Choose Format + Cells
Choose the Protection tab + untick Locked + OK
Highlight all the cells you want locked for your own use (use th
Control key to highlight non continuous cells)
Choose Format + Cells + Protection tab + tick Locked + OK
Choose Tools + Protection + Protect Worksheet
You can enter a password here
The other users can enter and change info in all the other cells apar
from the ones you have specifically locked. In order to change th
locked cells they will need the password.
For you to change them choose Tools + Unprotect Worksheet + enter you
password.
Don't forget to protect it agian once you are done.
Hope this helps
Judit
