Hi Alexander,
I’ll preface that I entered the user’s email (email field located in a tab only accessible by an administrator) info into a list item. In reference to the third rule, logged in user’s work email is checked to match email in the database.
As for the first two rules relooking at the groups’ rights who are administrators, they are essentially the same so they can be combined as one rule.
The interaction is logged in user is part of the administrators group and/or the logged in user (work email and database email match) are able to view the list item. If logged in user is not part of the administrator group and/or logged in user (work email and database email does not match) are not able to view the list item.
I apologize ahead for introducing another element in this concerning the edit form. The same rules can be applied to access the list item in edit form.
Thank you. Much appreciated.
