help with jquery
<p>This is what I am working on: </p>

<p><a href="http://jsfiddle.net/5Wxb4/" rel="nofollow">http://jsfiddle.net/5Wxb4/</a></p>

<p>I am trying to add an "adjust cost" function. </p>

<p>a. they enter qty = 1 for item1. The cost becomes 1x725=725. Install Subtotal is also 725. estimate total is 725.</p>

<p>b. they enter qty = 2 for item2. The cost becomes 2x100=200. Service Subtotal is 200.  Estimate total is 925.</p>

<p>c. hey enter qty = 1 for item3. The cost becomes 1x15=15. Service Subtotal is 215.  Estimate total is 940.</p>

<p>d. now, I want to adjust the total for item2. Say from 200 to 150. I need to show service subtotal = 165 and estimate total = 890. </p>

<p>I am using hidden fields like "oldTotal", "oldAdjTotal" to track what was the original values.</p>

<p>I appreciate any help...</p>
