I am trying to figure out a way, in which I can make changes to certian
cells within a shared document, however protecting the data from other
users.

Does this make sense?

Colulmn A has billing information that I want to have the ability to
change, but I don't want my account managers to accidently change any
information in this colulmn.

Please let me know if you might have any thoughts on how to accomplish
this.

Thanks
