title: JavaScript Global Var Hoisting Issue
body: <p>Here is my basic issue...</p>
  
  <pre><code>&lt;script&gt;
      var window.my_Global = false;
  &lt;/script&gt;
  
  &lt;script&gt;
      if(my_Global){...} //my_Global here is undefined, not false??
  &lt;/script&gt;
  </code></pre>
  
  <p>I know there must be a simple solution but I'm pretty stuck...</p>
