I have written a usage log into a spreadsheet to see who is entering the sheet, this is fine but some user names are not shown, only the time they entered, all macros are activated but there name is hidden, why is this?

Also if someone is in a sheet no matter what worksheet they are in and i try to go in, it comes up read only, but instead of it saying, "The sheet is locked for editing by FBF" i says " The sheet is locked for editing by ."

Anyone got any answers please

Thanks
