Hi,

Ive made a work book in microsoft excel for working out the cheapest mobile phone tarrif. One sheet is unprotected (admin use) and one is protected so nothing can be altered (customer use). Now i want to create a login sheet so the admin enters a username and password and gets taken to the unprotected sheet for editing and the same for the customer. Any idea how this can be achieved? i can only use excel for this so i was thinking of some kind of macro?

Any ideas?
