title: jQuery 1.4.4 error "q.replace is not a function"
body: <p>I've made a script that automatically calculates the total price for a invoice.
  Because I want to display the price with a comma instead of a point. I put <code>.replace('.',',');</code> on the javascript float value.</p>
  
  <p>But now I'm getting a jQuery error.
  The exact error is:</p>
  
  <blockquote>
    <p>Error: q.replace is not a function</p>
    
    <p>Source: http://<em>*</em>*.nl/cms/pub/jquery/jquery-1.4.4.min.js</p>
    
    <p>Line: 101</p>
  </blockquote>
  
  <p>And I use replace function as followed:</p>
  
  <p>Someone puts a price in a HTML text field and I request that value with the following code:</p>
  
  <pre><code>var price = $(this).find('.product_price').find('input').val().replace(',', '.');
  </code></pre>
  
  <p>This line works, but I'm getting that strange jQuery error.</p>
  
  <p>I hope that someone could help me! Thanks!!</p>
