Track changes and protect

[sglaser5916]

Hello,

I work with a co-worker on a spreadsheet report.  I am suspecting that they are purposely changing the information that I am responsible for completing.  How can I, stop this, and find out if my suspicions are true.

Thanks

Have you tried, you know, asking them? If they're co-workers, and not competitors, it's possible that they're not even aware of your expectations or of different roles.

We have had discussions about this and I was informed it is a gremlin.  Thanks for your suggestion.
