title: Update Textbox Values
body: <p>From the start I'd like to say I know very little jQuery - I've been using small scripts now for around a week now.  It is a useful tool, but I am unsure if what I am looking to achieve is even possible.</p>
  
  <p>I have a table layout as shown in this <a href="http://jsfiddle.net/dx6af/1/" rel="nofollow noreferrer">JS Fiddle</a>, an 8 column layout.  What I am looking to achieve is if the text is MATCH TEXT in column 2, row 2 and the textbox has the number 3 in it that this will then update the other two textboxes with a zero.</p>
  
  <p>I have found this slightly similar code from <a href="https://stackoverflow.com/questions/4567376/jquery-update-the-value-in-one-text-box-based-on-the-value-entered-in-another-t">another StackOverflow post</a>:</p>
  
  <pre><code>$('#txtAmt').change(function() {
      var txtAmtval = $('#txtAmt').val();
      $('#txtInterest%').val(txtAmtval);
  });
  </code></pre>
  
  <p>The thing is that while these sets of values appear in my table in groups of three, I might want to autoupdate the the 2nd and 3rd rows, or 1st and 3rd, or 1st and 2nd - so I don't think I can reference the name tag of the textboxes.</p>
  
  <p>I have searched the internet but I cannot find out if this is possilble or how to implement it?</p>
