Autopopulate Person from dropdown

[kmw1130]

I am trying to autopopulate a person field based on the selection in a dropdown.  The dropdown is pulling from another list, which I am getting a few fields, one of them is a person field.  I can get the value to populate in my person fields using this formula:

If(
FormNewPMR.Mode=New,
{
Claims: "i:0#.f|membership|" & Lower(LookUp(Office365Users.SearchUser(),DisplayName = ComboBoxProgName.Selected.'Account Manager'.DisplayName,Mail)),
DisplayName: DataCardValue63.Text,
Email: LookUp(Office365Users.SearchUser(),DisplayName = ComboBoxProgName.Selected.'Account Manager'.Email,Mail),
Department:"",
JobTitle:"",
Picture:""
},

Parent.Default)

But am getting Bad Gateway error.

UPDATE:  I figured it out, it was so simple.  I used the same formula that I used on the other fields from the dropdown, but instead of Default items, I needed to use DefaultSelectedItems.
