Good afternoon jerryjaysr

I have a template you are welcome to use. Each user must enter a username and password on opening the file, and only the sheets that they have been allowed to access by you in the setup page will be visible. You can also control whether a user should have full edit permissions on the sheet or read-only access. You as administrator would have access to all sheets.

If you (or anybody else) think you might be able to use this, then PM me your e-mail address and I'll forward it on.

HTH
