Require specific cell entry before saving file
 

I want to require the user to enter his/her name in a specific cell (E59)
before the user can save the file.
I tried using Data Validation where I specified Text Length between 1 and
40, and left blank the check-box for "Ignore Blank". Nope. I never
programmed in VBA, so I hope there is a simple solution (I might be OK with
some simple VBA code; would need where to put the code).

P.S. I posted this March 19th and again 20th 2008 and someone was kind
enough to respond, but Microsoft's link (in the auto-generated e-mail to me)
to the response did not work. I thank that individual for responding, and
ask that you please re-send your answer.
