Hi Paul, I got the code similar to this, but dont exatly how to edit this as per my requirements.
http://www.atlaspm.com/faqxlselfclose.html As I said in the first post, once he clik on hyperlink(i.e., in 1st sheet), it will count till 60 Minutes, and before 15 min it shud remind him. after 60 min it should protect and save it. Then he cant open tat as its protected. Regards, Vinu.
