I have a field form lookup tblContact with an "add new" button. I would like to set it up so that when the phone record is not found and the "add new" function is selected that the phone number that was being looked up appears in the "phone" field of the "Contact, add new record" window. How do I go about doing that?
In this use case you should change your lookup to a drop down list. When users do not see what they need, they will add record and that new record will auto populate in the drop down list.
