title: paypal payments advanced missing token error
body: <p>I've been trying to get a transaction through on a PayPal payments advanced account for a few days now with no luck. I've done some searches for an answer, but none seem to fit. Here is what I am doing: I get a secure token with something like this:</p>
  
  <pre><code>USER=myuser&amp;VENDOR=myvendor&amp;PARTNER=PayPal&amp;PWD=mypassword&amp;TRXTYPE=S&amp;AMT=750&amp;CREATESECURETOKEN=Y&amp;SECURETOKENID=1394403275938
  </code></pre>
  
  <p>This is sent to <a href="https://payflowpro.paypal.com" rel="noreferrer">https://payflowpro.paypal.com</a> and gets the token fine:</p>
  
  <pre><code>RESULT=0&amp;SECURETOKEN=XgOx4ldQQgE2z7UeTalxMAgdu&amp;SECURETOKENID=1394403275938 &amp;RESPMSG=Approved
  </code></pre>
  
  <p>I have my hosted page configured for layout C, and after getting the token I try to open an iframe with something like:</p>
  
  <pre><code>&lt;iframe src="https://payflowlink.paypal.com?MODE=LIVE&amp;SECURETOKENID=1394403275938&amp;SECURETOKEN=XgOx4ldQQgE2z7UeTalxMAgdu" name="test_iframe" width="570px" height="540px"&gt;&lt;/iframe&gt;
  </code></pre>
  
  <p>This always ends up with the iframe filled with some error html, indicating:</p>
  
  <blockquote>
    <p>Some required information is missing or incorrect. Please correct the
    fields below and try again.</p>
    
    <p>Error: Token is missing. Please return to the website from where you
    started your purchase and try again.</p>
  </blockquote>
  
  <p>What am I doing wrong? I have verified in manager.paypal.com that the account is set to live mode, and I've tried getting the token with both the default manager account and a new user I created, but both end up with the same error page.</p>
  
  <p>Thanks!</p>
