I managed to display my max9814's value on the firebase

When it reaches a certain level, I want to store each set of data values separately.
for example
orginal1=365
original2=200
original3=266
I wanted to save all values separately by setting the count value to a variable name as follows.

However, at my level, if I save one data, the existing value is initialized and newly saved.
How can I do this? Thankyou!
