I have a form where a user can either enter a new claim type or change an existing claim type. If they change the claim type code which is the key and there are related records in another table, they currently only get the standard error message "The record can not be deleted or changed..." when they tab to a new record. I also have a close form button on this form and I need for that button to have a similar error message attached to it so that if they make a change and then hit that button they are informed that their change is not going to go into effect. We do not want to allow cascade updates so they just need to see a message letting them know they need to change it back. Can anyone help?
