How realtime database work´s?

Hi guys, I will need a lot of patience from you, because I still do not understand how this works

To try understand i create a new project and put this blocks:

and after this i run…

why it appears undefined?

I have sure i put the correctly API KEY and Database URL
When i click to save, should something happen in the firebase database? because i not see anything happen

Thanks for a lot of patience.

  1. Make for each parameter a separate display in the Label.
  2. Check the value of the “error” block
