Using Access2003, we need to send out a file to each office. They input 5
fields which then generates (calculates) a special code.

Whilst we are not concerned at the number of staff that will have access to
the database...we do need to protect the formula that generates the special
code. At the moment the formula is is in a unbound text box on the input
form.

What is the best way to protect this very sensitive piece of  information.
