Firebase doubt regarding data entered

hi all had a small doubt that how can i make a system like for every user that enters his/her name in the textbox then his/her name will be stored in a textbox
i tried a code but what is happening that whenever i try from other device it changes the current name entered

my code


The tags in Firebase are global to your project, so if everyone writes to the same tag, "name", then they will overwrite one another. If you really want to have everyone's names show in a single tag, you probably will want to use the AppendValue block to add people's names to a list.

ok sir thanks for your help :relaxed:
