[Xsltforms-support] sending xsltforms submission to PayPal for processing - possible?

[Alexander Ž. <sa...@st...>]

Have any of you managed to accomplish this? I have a 3-product  
ordering xsltforms form. I would like to send the data the form  
collects for payment processing to PayPal using this submission:

<xforms:submission id="s01" method="post" ref="order/paypal"  
replace="all" action="http://www.sandbox.paypal.com/cgi-bin/webscr"/>

Using FireFox and Safari on Mac I am getting an error when submitting:

1 -> "Submit post - undefined - http://www.sandbox.paypal.com/cgi-bin/webscr 
  - true

The full error trace is shown in an attached image (not sure if it  
makes it through to the list - if not and somebody will react to this,  
I will retype the error):
