Creating a formula
I want to create a formula or a scritp to prevent users to change the data in some fields of my table. For example:
I have the following fields in my table:
Name: (empty) List number: (empty) Number of Essays: (empty)
Then a new record (users can create as many records as they need to) is created in my database with the following information
Name: John Doe List Number: 10 Number of Essays: 4
Users can change change the Number of Essays field any time they want in the future. However, I don't want them to change the neither the Name nor the List Number fields once the information is entered for the first time. Can anyone help me with this, please?
