Check your firebase’s properties. Project bucket should be empty in order to work

But that one is the solution all other settings are same i just empty the project bucket and it works anyway i marked your first reply as a solution

Wrong firebase’s settings resulted in not getting value from firebase so get value was empty string and math operator gave error because math blocks do not work with empty strings

Ok i got it Thank you once again
