variables showing as undefined in firebug when they are defined
<p>here is my site <a href="http://iadprint.com/products?product=Business%20Card" rel="nofollow">http://iadprint.com/products?product=Business%20Card</a></p>

<p>when i select a value for quantity a price is supposed to show in the pricing div on the top right.
this used to work but for some reason today in firebug under dom i can see that a few variables show undefined. when i do the ajax call  iadprint.com/ajax.php?id=1 the data shows correctly and the variables in the js are all defined. what can be wrong? here are the variables that i am seeing undefined.</p>

<pre><code>woCoating_price
woColor_price
woDesign_price
woJob_Name_price
woPDF_Proof_price
woQuantity_price
woRound_Corners_price
woTurnaround_price
</code></pre>
