little jquery calculation
<p>I need some simple calculations done using jquery.</p>

<p>This example <a href="http://jsfiddle.net/tbL5r/" rel="nofollow">http://jsfiddle.net/tbL5r/</a> is pretty close. It just needs a little tweaking:</p>

<ol>
<li><p>the user should input the price.</p></li>
<li><p>I need the sum of the all prices calculated.</p></li>
<li><p>It should calculate without clicking buttons.</p></li>
</ol>

<p>Cheers and Thanks</p>
