Hello there 👏, great job working on this project, I checked it out and it's great, I have a suggestion I hope you don't mind..

You wrote a message "you havn't choosed", that will show when the user hits the submit button without giving a rate, I like this and I think it's good, also there's an alternative, that you could use the "disabled" attribute so you would disable the submit button at first, so when the users try to hit the submit button without giving a rate they won't go to the next page, and when they give a rate you could remove the "disabled" attribute.
