Adding number to the list and the number will save to the firebase database

Hi, I'm new to MIT App Inventor been trying to figure out how to fix this problem of mine, I want to save every number that the user inserts into the textbox on a list picker, the user then can pick the number they want, it will also save into the database so if the user logout or quit the app the Numbers will be saved. This is the format of the block, I know it's confusing, but like I said I'm new to this language.
