急! 在 www.sbb.ch 上购票的问题

准备购10月份的票:


1. 提示"Please select a date within the valid date range: 12.08.2009 to 11.09.2009." 什么意思?


2. 似乎只有以下的卡可以打折扣:


"The following options could reduce the price of your journey:

1-year Half-Fare Card Artikelinfo

Day Pass add-on to a Half-Fare Card Artikelinfo

Half-Fare 9 o'clock One Day Pass Artikelinfo"

但我如果只有SWISＳPASS 怎么办?


谢谢.
