track changes

[SBES]

Trying to use a study guide for Office. A practice task is instructing me to
turn on 'Track Changes' on a sample worksheet but on the Review Tab, in the
Comments group, 'Track Changes is not able to be clicked. Can't seem to
figure out what I didn't do.

False alarm,. It came to my attention after pondering upon the dillemma that
the file was a read only document so certain features were unable to be
accessed.
