I combined both of your JS-codes, everything works great, thank you!

However, there is 1 problem: for some reason, if someone clicks on my test's link that I send in a personal message in social media (at least, in VK), then only in a mobile phone's version (both IOS and Android) autocomplete doesn't work! But if I copy this link and paste it in a mobile phone's browser, then autocomplete does work ("Enter" button for sending the results always works btw). Is there any way how to fix it, or it's a social media's restriction?

And I have 1 more question: In our previous conversation you sent me a CSS-code that can hide the results from a screen for certain quizzes. However, I had to turn off "Show questions at the end" and "Show right answers at the end", so people couldn't see them and the results would be send only on their emails. So my question is: Is there any way how to send these people a link in email on my Trivia test, where all the right/wrong answers of this test will be shown? So users will not only see the amount of right/wrong answers in email, but also see where exactly did they make mistakes/right answers.

Thanks in advance!
