How do I fix this code?

Question

I was working on a random Sentence generator but apparently it doesn't work. Is there a bug in it or is there another way to do it?

Answer 1

1. comment line 1( window.onload = function() { ) and line 16 ( } ) with simbols //
2. move line 5 ( var out = document.getElementById("out"); ) into the body of function "generate"
