Not sure what I'm doing wrong with this code...

Creating a "for" loop from 4 - 156

script.js 
for ( var num = 4, num <= 156, num++ ){
  console.log(num);
}

Inside the for loop setup you need to use ; semi-colons instead of , commas. Just a syntax error thing - your thinking is correct. :)

Thank you, another quick question, why is there no semi-colon after 'num ++'?

In this case, think of the semi-colons as separators to break up the expressions. Because you're ending the expression block with ')', you've already flagged that section as complete to javascript.
