Error message in Firebase DB

This problem only calls me when I use get value

The error is regarding the and block (Logic section). Check it. Also you can you show your blocks, if you want.

Maybe you should read what the error message tells you…


This also happens when I submit a value

You dont need the second true Check for is empty .
Is empty returns true or false

Why do you show us your database?
You should refactor your logic in the blocks

so this is the problem?

You should give it a try what I wrote
