Hello ksap
The price initally displayed as part of the connection overview is a “From”-price, the cheapest price possible. This being either a Supersaver ticket or a ticket which requires the Half Fare Card (½) in addition. Most people living in Switzerland own the Half Fare Card.
Supersaver tickets are not recommended if you arrive by air and connect to a train.
Without knowing the total number of persons travelling as well as their age we cannot verify the total cost. If you want us to help you, please tell us the date of travel and before-mentioned details.
Alternatively, check for Saver Day Passes:

Or, the Swiss Half Fare Card, worth if you spend more than CHF 240 per adult on travel costs, and, children up to 15.99 years travel for free with the complimentary Swiss Family Card.
