Hello Riekoashoorr55
Welcome to the SBB Community.
We are a customer support forum run by volunteers; we are always happy to get some greetings.
What concerns your question:
In order to make group bookings online, you must create a customer account first as it is not possible to book group tickets as a guest:
https://sbb-tickets.cc/de/angebote/swisspass-karte/register/2
Alternatively, you can call the SBB Contact Center to make your bookings: +41 51 225 78 56 (24/7, waiting times may be possible).
Ps. We cannot access your URL, and won’t click on links that we do not know.
Kind regards,
Roland
