You need to show more of your firebase console data, to include the vehicle number ?

What do you mean i cant comprehend show more of firebase console data, my screen 2 design is where i put the vehicle number that are already on firebase and if the vehicle match to the firebase then it retrieve the data such as color, date, make, model and if it doesn't detect it would show no not found

None of the other data uploaded is related to the vehicle number.

How will you store vehicle No 11, without removing the values for Vehicle No 10 ?
