Hello, I was trying to create a chatting app with Thunkable.  
I am able to see the typing part of the user input, but when I click the “send” button, the input doesn’t appear on the List\_Viewer.  
Does anybody know what is wrong with my code?  
I will upload the screenshot of my screen with the chat and the blocks.

Have you confirmed that data is getting saved to Firebase? If your rules or authentication account are not correct, that won’t happen and then the `when Realtime_DB1 DataChanged` event block won’t fire.

Have you debugged your blocks to find out what is/is not firing? One simple step would be to put a set Label’s Text to “test” right after the `set List_Viewer1's text items` block. When you preview, do you see “test” in that label?
