The XML below has an expression that works.
What if I want to change this expression to have a conditional: the result must be blank if person.mobile_phone is blank.
Thanks
1<update_person>2 <person>3 <person_id>@person_id</person_id>4 <alt_email_address>@expression[person.mobile_phone + "@textmarketer.biz"]</alt_email_address>5 <insert_update is_initialized="False" />6 </person>7</update_person>
