I actually need a couple more calendars, aside from the three places provided, added to the sidebar widget. I see there are three and tried to make adjustments in google-calendar-widget/ko-calendar.php but I am not having any luck pulling in the data for the additional calendar.
While I was able to get the widget to add an additional input line 4, the additional calendar title still reads 'Calendar url3 (optional)' even though I made the changes adding url4 in a number of places within the google-calendar-widget/ko-calendar.php
Otherwise the calendar works fantastic. I am so grateful to have found it. Can you help me out with this.
