Default value for lead copied from contact
I have tried set up default value for lead address record to be the same as contact by using JoinFieldValue as below, but it doesn't populate data in to addess
JoinFieldValue('<Contact>',[<PrimaryContactId>],'<AlternateAddress1>')'+'JoinFieldValue('<Contact>',[<PrimaryContactId>],'<AlternateAddress2>')
Is there any workaround I could do to make it work??
Many thanks, Kasia
