as it was saying previous value is empty so i set its initial value to some small number but when i try to append it again says previous value was empty but it is not empty in the Firebase
i have set its inital value to small number so that it wont make error but still the error persists.

Did you debug it?

nope, couldnt find its solution still saying previous value empty

Is your value stored in the correct path? In the place of use append , use a label and try to get the value in a label. If so your path is correct. If you are not getting value then there is a problem.
