I have made a booking form with two payment methods (bank transfer / paypal). Had some problems with the setup but now this works (thanks for the good and quick support bei CP!).
Two things for me to solve yet:
1. After the paypal payment there is a redirection to the "thank you" page which I created before and then inserted the URL into the form processings / email settings.
BUT I need a redirection also after choosing bank transfer and hitting the submit-button. After that there is just a white page (with correct header and menu and sidebar). That is rather confusing for the customer not knowing if data has been sent correctly. Confirmation emails are sent correctly but without any redirection to another page this simply looks unprofessional (booking process seems not to be finished)...
2. In the confirmation message I can use the fieldname to add data/values of the filled in fields into the email and this works fine.
I want to insert a fieldname into the email subject (f.e. your booking for event <%fieldname11%>) but this doesn't work, you just see <%fieldname11%> but not its value/data.
Also in the "thank you" page after paypal payment I have set the fieldnames, but no values are shown, only <%fieldname11%> etc.
Looking forward to any help for this, thank you.
