Answer 2

You are calling the DOM selector code before your html document is read.

put the script after the those element or wrap it onload

window.onload = function(){
//js code
}

Yeah, hello is not definied. Quote it or define a function/variable named hello.
Like "Hello"

Or

var hello = "my variable named hello"
