Many-to-many relation

Hi.

I have 3 tables: CONTACT, PERSON, CONTACTPERSON

CONTACT: ContactID, ContactName
PERSON: PersonID, Firstname, Lastname, Phone, Email
CONTACTPERSON: CustomerPersonID, ContactFN, PersonFN

Under table CONTACTPERSON, I would like to add several Persons
ADD: PersonID (Store PersonID in database, but Lookup from PERSON Fullname with phone)
List: CONTACTPERSON, I would like to inline edit Phone also)

How can I do this in PHPRunner?
