If he chooses deposit, I calculate 30% of the total amount.</p> <p>Now, I have to make the php hook to replicate the behaviour before sending to paypal but I do not understand the parameters I have to deal with to make it.</p> <p>I have read a bunch of doc about it (form entry, gform..., etc.) but it is still a little bit dark.</p> <p>Can you show me the way ?</p> <p>Regards,</p> <p>Frédéric </p>
