J's Calendar. 2 on same page don't work!

[espmar]

1) Script Title:

2) Script URL (on DD):

3) Describe problem: A holiday booking form with 1 calendar for arrivals and immediately below, another for departure dates. The day's date correctly loads when accessing the page. On selecting the arrival date calendar it works fine, but when selecting the departure date calendar, it changes the first calendar settings. Is there some script missing somewhere?
