Dears,
I'm new in PowerApps.
I'm trying to create(customize) Form for Sharepoint list.
I have "Vehicle List" list as data source.

I created "Vehicle" List for workflow.

I used lookup in "Vehicle" list in column "EmpName". And now users can select value.
I`m trying to use auto population of "EmpPosition", "CarNumber", "CarModel" based on "Vehicle List" List , but it does not work.
I think I'm doing something wrong.
Сan anyone advise how to do it?
