Some body can help me?? Is very urgent to me finnish it. I promeis don´t back to use Animate cc! :-(

Thank you KGlad for everything, the help you have given me and for the time you have used. It is true that I am not a user of animate, nor was I a Flash user and before that I was the Director of Macromedia, which is the grandfather of Animate until Adobe bought it to later release it as Flash. But the truth is that although this also had its own thing, but it was not even remotely close to Animate cc, which in my opinion has things that are already escaping all logic. Of course my lack of knowledge in coding is a big enough limit to tackle a project that is too complicated... but this is not it. It's the simplest thing you can do... buttons that come and go to labels, others that make calls to the www and a couple of movies. When I decided to do it, I didn't think it would get complicated with things like for example buttons that don't work (without knowing why) but when placing them in a higher timelime position they suddenly work... this if there was something in between timeline nothing relevant that could be the explanation of why they did not work before. Now I've solved the problem with the buttons in the puppies section, simply taking the movie to the main scene suddenly works perfectly again (now the only thing is that instead of 3800 frames I have 8500, but hey... it works that is what I want to be able to start putting up the posters in search of adopters of the puppies (puppies when I started doing this project with Animate cc... we'll see how they will be when I finish it) Why now (I did the test when I passed the movie of the first puppy to the main scene and it worked well, also the second... and once I verified that everything ran perfectly and the buttons worked correctly... when I finished and published it, again the screen was blank ! that they do not do the same with Figma. Thanks again for your help and time spent.
