I've taken yoour database that we created in the lessons and made it a front end/back end system where only the tables are in the back end. If I have all of the forms and queries in the front end and I want to make a check box field called "approved" on a form named LeadDetailF which uses LeadDetailT but I want it to do something like this: IF the box is checked THEN 3 different fields in the LeadDetailT cannot be updated by anyone. I'm trying to lock down 3 fields in the table because there will be a dozen people in my office that will have the front end db on their PC so I can't lock down forms, or can I? If so, can you tell me the code?
