Answer 1

The code is correct but it seems that after I click the Submit button it says that

www.youtube.com refused to connect.

And I suggest that instead of using second name, try using last name.
This makes the form not complicated as for the ones with a three name format or for other names

/first name/ middle name/ middle initial/ last name/

Hope these suggestions help you.

Just keep coding mate.
You are now creating projects so keep it.
