Hello,

I have a spreadsheet that was setup by someone else, it has a setting on it
that tells a user the file is in use if they try to open it while someone
else has it open. I can't figure out how they set that up.

I was wondering if someone might have done this before and can provide
instructions on how to set this up.

Thanks,
