Maybe there is some paypal developper experts around to help me ?
I'm trying to create a form field (for the VAT number of my customers) to be sent through my IPN and orders database.
I was thinking using the "on0" paypal custom variable as the "custom" one is already in use in my code.
<input type="hidden" name="on0" value="VAT">
<input type="hidden" name="os0" value="123456">
But it doesn't seems to work :/
Anyone has already experienced that ?
