Password Fields and If/Else Statements

hi!

I´m using this simple code similar to a tutorial here on kirupa, where you put your password and if it is valid it redirects you to a URL I defined, you can see the AS in the “Go” button. My question is how can I add another field for username not just a password? I tried some things but no luck :frowning: maybe someone can point me in the right direction and tell me what to do :cons:

Thanks!
