Hello,
I've followed @ShaneYoung's great video on repeating tables here
On my save button, I am using this Fx:
Patch(colDocData, ThisItem, {Subtopic: Subtopic_dd.Selected.Result, Argument: Argument_input.Text, Evidence: Evidence_input.Text}); Collect(colDocData, {Subtopic: Subtopic_dd.Selected.Result})
This is clearly sitting in my collection:

However, when viewing the saved item in my app, the fields are blank - what gives?

Any help, I would appreciate! 🙂
