Hi! I am new to App Inventor and I am trying to build an screen that acts as a schedule where one can add events and they will appear on list viewer. I created it last night and it seemed to work fine. Today I accidentally backtracked and deleted some code. I do not know how to fix this, I get a notification (shown below)

Please help, this is my current code ( user must enter event details to add to list viewer) Thanks! Let me know if you need more information

This is what the screen looks like on my phone! It is suppose to be for softball games/practice. (entered values are just for testing/example)

ignore the other screens sorry it is under "calendar"
it looks your eventData is contaminated by bad data from tinyDB, try call TinyDB.ClearAll.

This fixed the issue, but now the data is not appearing in the listviewer (elements) Does anyone know how to fix?

Sorry I worded that wrong! I meant I keep adding new data and it is not appearing on the listviewer. How might I fix that?

I see mine.
Try applying Do It to the global
I see two possibilities:
You have white background for the ListView, but its text has reverted to white ink, making it invisible?
Your screen is scrollable. Maybe the ListView is out of view?
By The Way, why do you test for some components Disabled, when you never disable or enable them?

I'm sorry, I do not really understand what you mean when you say "Do it?" Can you maybe specify? Thank you.
