It is hard to see what exactly you're doing wrong with your <code>runCSStweaks()</code> function because we can't see your HTML or how you're calling it. You can see in <a href="http://jsfiddle.net/jfriend00/kk2U9/" rel="nofollow">my working demo</a> that the code works fine and populates the <code>item</code> array just fine when nothing else is wrong: <pre><code>var item = []; function runCSStweaks() { $('.jp-playlist li').each(function() { var min = -90; var max = 90; var random = Math.floor(Math.random() * (max - min + 1)) + min; item.push(random); $(this).css('-webkit-transform','rotate('+ random +'deg)') }); }; runCSStweaks(); </code></pre> Working demo: <a href="http://jsfiddle.net/jfriend00/kk2U9/" rel="nofollow">http://jsfiddle.net/jfriend00/kk2U9/</a> that shows the <code>item</code> array fully populated with random numbers. I've exaggerated the rotation just for visual clarify. The possibilities in your own code/HTML I can think of are: <ol> <li>The selector <code>'.jp-playlist li'</code> isn't matching anything because that isn't the right selector for your HTML.</li> <li>You're calling this code before the page has been loaded so <code>.jp-playlist</code> isn't found.</li> <li>You're calling this code before the <code>.jp-playlist</code> and <code>li</code> elements have been created (if they are created in code or loaded dynamically after page load).</li> <li>You're getting confused because there's no <code>item[0]</code> element in your code that way you are populating that array (that's why I used <code>.push()</code> in my code).</li> <li>You aren't calling <code>runCSStweaks()</code>.</li> </ol>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
