- Double-check your TinyDB tags:
- Make sure both saving and retrieving operations use exactly the same string—matching in spelling, case, and punctuation.
- Review your layout and events:
- If you’re using multiple screens, consider merging them into one and using layout containers (like VerticalArrangement) to simulate screen transitions.
- Rename your buttons meaningfully (
btnSave,btnHelp) to avoid confusion when wiring up events.
