Thanks, that helps, I suppose there must be a similar way to cancel what they bought if the payment didnīt go through.
Also the problem is the button, I think the way I posted above maybe will work as I found it in paypals developers forum.
As I need to add the price dynamically.
I will have to do test with the sandbox.
Not sure if I should but I have activated automatic return and also I activated PDT.
The IPN I will have to add to my site I understand, what a mess lol.
I suppose if the person arenīt suppose to register I will need a good catcha that works perfect not to do robots do bookings in the database.
Anybody know a good catcha or similar to know its a real person?
I dont use as I dont like them, but here I have no choise.
