[Zope] Extended use of the calendar tag

Hi! I have a question related to use of the calender tag. If I have this code: <!--#calendar mode=month--> <A HREF="/some/place/form"><!--#var date fmt=day--></A> <!--#/calendar--> Then - is there some way that the DTML method 'form' in /some/place/ can pick up what 'daylink' that was the caller, or is the only way to transfer variables between methods to use forms? I hope there is a solution to this as it would be fairly simple then to create an appointmet calendar kind of thing. Greatly appreciate your help! Sture Lygren
