In this lesson

Prepare for the AB-410 exam (Building Intelligent Applications). In this lesson: global and context variables, collections with SaveData and LoadData, named formulas and user-defined functions in App.Formulas, component libraries, and error handling with IfError, the Errors function, and App.OnError. Includes three original practice questions.

Preview the topics
  • A Contoso screen shows a details panel when a technician taps a button, and no other screen uses that value. What should hold it?
  • Contoso’s status colors are computed in OnStart into a global variable, which slows the start, and one screen accidentally changes the variable. What’s the better approach?
  • Contoso wants every unexpected error logged and replaced by one friendly message, without wrapping every formula. What should the maker use?
