How do i set a variable using conditional statements?
<p>This does not work, even though putting a simple print ("foo") in the function block does work. </p>

<pre><code>&lt;script&gt;

var viewportHeight = $(window).height();
var X;

$(function() {

    if (viewportHeight &gt;= 600) {
         var X = 100;
       }
});
&lt;/script&gt;
</code></pre>
