Morning all.
I just received an error while trying to run a macro. While this is the
first time I've operated on this workbook, I did check the information that
the error message provided and it doesn't appear to apply on this file.

Here is the message I received:
-------------------------------------
run time error 1004
you cannot use this command on a protected sheet. to use this command, you
must first unprotect the sheet ( review tab, changes group, unprotect sheet
button). you may be prompted for a password.
-------------------------------------

I went to the review tab, looked at the changes group, and there is no
"unprotect" option. I then clicked on the protect workbook icon, and it says
unrestricted access. I then tried clicking on that, and nothing changes-- as
it's already checked.

Any ideas on how to resolve this?

So far I've been able to run other macros with no trouble, so I'm a little
stuck/confused here.
Your helps are deeply appreciated.

The macro that I'm running is one that I obtained from Thomlinson.
Thank you.
