Problem Filtering by Number of Feeds on Reverse Sort - gAjax RSS Feeds Displayer

1) Script Title: gAjax RSS Feeds Displayer

2) Script URL (on DD):
http://www.dynamicdrive.com/dynamici...sdisplayer.htm

3) Describe problem:
I am trying to use this script to show the next calendar entry that will be appearing on a google calendar. I have two issues ...

A) As a test, I created a google calendar with three items respectively appearing on three different days in the future. Since the script sorts by the most recent by default, it shows "the most future" rather than "the next." I found this helpful item in the forums, which is supposed to reverse the sort order. And, it sort of does. If I show all three items, they now appear in the opposite order. The thing is if I only show one item, whether reversed or not, it always filters it to show only the most future item ... shouldn't it always show what is at the top of the list first?

B) I'm assuming that the gCal XML feed will only show right now until dates beyond. If it doesn't, and I reverse the order, then I might be showing the oldest entry rather than the soonest entry ... is there a way of querying a specific date range?
