Looping forward items in an array
<p>I'm trying to create a job roster for my Boy Scout Troop, and I'm having a bit of an issue generating jobs.</p>

<p>I've got an array that contains jobs for the people. I then use a loop to display a job associated with a person.</p>

<p>Is there any way I could have the job move one up?</p>

<p>For example:</p>

<pre><code>Person 1     -     Job 1
Person 2     -     Job 2
Person 3     -     Job 3
</code></pre>

<p>That then goes to:</p>

<pre><code>Person 1    -      Job 2
Person 2    -      Job 3
Person 3    -      Job 1
</code></pre>

<p>And then</p>

<pre><code>Person 1    -      Job 3
Person 2    -      Job 2
Person 3    -      Job 1
</code></pre>

<p>But because users can change the number of people in a group (from 2 - 20), how could I make this process happen without hard-coding it?</p>
