Good evening, gentlemen, I am creating a simmple form in javascript and html persisting in firebase, but this firebase error appears - Uncaught ReferenceError: firebase is not defined. I searched in several places and all the codes that appear are according to mine and therefore I have no solution.
Can someone give me a light?
