Hello,
I am using the 'Edit form' canvas app control, which is relatively new to me, to recreate model driven forms' functionalities in a canvas app.
Among said functionalities is being able to set some fields to read only and set their data to some value of another lookup field's data.
This isn't exactly like a model driven app's 'quick view' form however, let me explain: (and have a screenshot of the form)
For the record, this form is set to FormMode.New

So... the user picks a position, and I want to show the position's job in the form, which will subsequently be set as the new record's job.
As far as I know, it should be as easy as referencing the position dropdown, then plugging the position's job record into the job field then displaying its name.
The way I'm doing it is by setting the Job field's data card's default value to the Position dropdown's job record,
I've researched and asked my colleagues to no avail, so I turn to this community for help. Any suggestions, and perhaps a refresher on some intricacies of the edit form I may have missed would be greatly appreciated.
