Re: Protecting Cells from accidental change

Thanks to all for information and ideas. The documentation was a little misleading on that point and I have now achieved the main thing I want which is to be able to protect the work I have done but leave remaining rows unprotected so I can easily add new data. I will only have to temporarily unprotect the sheet to correct mistakes. Automatically protecting cells that I have entered information into would be nice as then I would not have to protect them for example at the end of each session of data entry and also they would be protected during that session. I was wondering if the protection could be applied to cells on the condition that they were not empty.

Michael, I will play around with that idea. It does sound complicated but might be useful in some situations.

Best wishes Steve

Good morning,

I have a suggestion, but it may not be applicable to a Gnumeric table
which is already in use or has evolved past the stage, where
modifications are easy.

I suggest that the formulae which are usually there to calculate
“results”, be it intermediate results, are accumulated in one table
(“sheet”) and the original data, which you may wish to adapt or complete
frequently, stay on a different sheet, where they are looked up in your
“results-table”. This way, you can easily protect the whole sheet, which
protects securely your formula without impeding calculations on new

If you use the existing protection on whole sheets, a message-box is
already generated each time, that you try to alter cell-content.
