When paying by credit card: After clicking the payment link, “0” is displayed as the amount to be paid. What does this mean?

This can have several causes:

• On the one hand, you and your fellow travelers may have already paid the outstanding amount in full.

• On the other hand, when paying the 2nd installment for the land program, an outstanding amount of 0 may be displayed if the payment has not yet become due. In this case, you can wait with the payment until the due date or manually set the amount to be paid according to the invoice. To do this, click on the amount (0) and then enter the amount to be paid yourself.
