prevent cell values modification after saving the worksheet.

Hi All,

I want to prevent cell value modification for example if I write “A or anything in cell “A1” then … after writing and saving the file I and anyone else should not be able to delete or modify its value.

Means the cell which have contain a value should not be deleted/modified by anyone and blank cell should be able to write and edit for anytime by anyone but when blank cell get a value & worksheet get saved then it should not be deleted/modified.


Please help me to get this one.. Thanks in advance .
