Displaying a "could not find deal number XXX"

Hello again.

I made a custom code at the end step when a certion payment is choosen, then it displays an iframe to creditcard billing.
the problem is before i get the i get the "could not find deal number" and the cart is empty before i get there.
the cart configuration is to be emptied when "confirmed", and this requires the verfication of the iframe.
so the cart is emptied, the order exists at "created", but Hikashop cant recognize it..

What might be the problem?

Let me put it another way.

I noticed when the checkout reach end i made another step require to choose between 2 options and click next.
When i click next (at the first time only) i get the order could not be found and i am logged out.
When i log in back i continue from where is stopped, i get the thank you page, but the onPaymentNotification() is not working and another deal is created with no value. (Like clicking the new button at the back-end).


My question is how can i extend the session for the checkout? and does it can be that i am too much time in the end step so he kicks me out?

No it wasn't the problem. Apperently my editor thought an note has { so it did not close the payment banktransfer the right way.

Thanks anyway.
