Good morning @samiu8336
I put the add items block in the list, but when I do that, in firebase the data added in the selected tag does not appear.
Can you help me see where the error is in the blocks as follows?
Thanks

Do it this way:

Hello Friend.
I already did, but this way the new data replaces the old one. And I don’t want that.
I want the new data to be added to what already exists in the database.

you are doing it wrong , you are adding items to wrong list, and not saving that to fire base,

Problem solved. I had to go get other sources.
But thanks to those who tried to help. Thanks
