A Dictionary from a JSON file

MIT App Inventor Help
1

My app does nothing but read a JSON file in which I have edited my dictionary. See the attached json file.

MyDict.json (330 Bytes)

Selecting a language from a listpicker displays the four nouns in the selected language.

That's it.

However, it doesn't work; I still don't seem to understand how the dictionary works in MIT App Inventor 2.

I'm attaching the blocks and a screenshot of the app installed from the apk file on my phone with the failed operation.

Why isn't it working? Where am I going wrong?

Any advices will be appreciated!
