Why does this happen, is it a bug or an issue in my blocks?

You now have three separate topics about this issue. It’s confusing for me to try and help you because the information I need is in those other topics. It’s generally best to post more details on the original topic so that we can follow along with what has already been suggested.

Telling us “it just doesn’t seem to work” is not enough information to help you. What is it supposed to do? What does it actually do? What does the Firebase data look like and have you included it as text in the post?

Here are the other two topics: How to show specific information from a table of real time firebase database - #2 by marion.dorsett and How to create relative search - #4 by marion.dorsett
