Data Validation

Hi I have a problem with my LOGSHEET (please see attachment). User is able to delete the contents of the cell J12 or the selection from the drop down.
I want user to choose only from the drop down and not to delete the contents of the cell.

What I did is locked the cell and protect. User cannot delete the contents but cant choose from the drop down contents also.

I don't know what to do anymore. please help.


Thanks.
