how to keep forms unchanged?

[codedreamer]

Hello,

I have a form with formulas and vba code. The code is password protected and the document is read only, but when is saved as the cells can be partially modify.
what can be done to prevent this from happening? Thank you for your help.

Could you save the file as a Template (.xltx)? That way, user opens the file, makes changes (why are they doing this?), and closes, but your original stays unaltered?
