Hi,



there is a list where employees enter data about internal damages done by forklifts.
In this, there is a column where they are to enter a name if it is sure who was driving - if not, they are to just leave it empty.
There are experts, however, who write something like "known" or "unknown" or whatever in that column.

=> Thus my question: Can I implement some kind of data_validation so that people can only enter some real name, maybe based on the criterion that a real name has 2 or more segments? (I don't know what else could be the criterion, but any ideas are welcome).

Thanks a lot!
Best regards,
