LookUp Field and Auto Population

[johnbradbury]

Afternoon all (apologies for all the questions this past week, I'm really intrigued by PowerApps now and I just want to know everything!).

I'm creating a form which has a lookup field to contacts but I'd also like to include a number of other associated fields such as telephone number, business name etc... all of which are stored against the contact record.

Ideally these would auto-populate when the contact name is selected (I used Dataverse).

1. How do I ensure related contact fields auto populate?
2. How do I ensure they populate with the required data and not just show the contact PNC field?
