Multi Scene Swapping not works

Hi. I’m working on a Multi Scene swapping with localhost. I don’t know why when I test it in browser is all blank/white page and console give me any error. Why?

Sorry there is insufficient information to help. Does your code work in the playground? Does each scene work individually? Have you copied the code correctly?

I wanted to post entire code befire, but i don’t understand how i can insert in this post ;(
As you suggested me before, I’ll verify if my code works in playground or not.

Finally, I’ve solved. Issue were the links script not updated.
