  <p>I have my own separate test file and all variables are visible after clicking <em>BUY NOW</em> button.<br />
  I've checked different values, but they are not visible on paypal (except the <em>itemNAME</em> variable).<br /><br />
  What could be wrong there (<a href="http://codepad.org/WuLakyvT" rel="nofollow">link to code</a>)?<br/><br /></p>
