URGENT
after update the reservation form doesn’t work!
In the form, the first day is never count in price… if I select 1 or 2 days in reservation form I have always the price for only 1 day!
The price is wrong in reservation form but it’s correct in the box with paypal button, in the backend and in the email that you receive.
Please help me as soon as possible because I have to public website today and I can’t have this problem on reservation because users must know the right price since the beginning!
Thanks a lot for a quick answer
