I checked out your page and it was doing the same thing mine was.
Check at the top of your page and change this
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
to this
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
You also have to change the code for calendar placement
Change this
<td valign="center" align="middle">
<!-- This is where the calendar HTML will be inserted -->
<div id="cc_webcalendar">
<p>Error, content did not load.</p>
</div>
<!-- this loads the calendar -->
<script type="text/javascript">
var maxdate=new Date("11/01/2011");
var mindate=new Date("08/01/2010");
loadTodaysCalendar(mindate,maxdate,"church_calendar");
</script>
To this
<td valign="center" align="middle">
<!-- This is where the calendar HTML will be inserted -->
<div id="cc_webcalendar_container" style="width:400px">
<p>Error, content did not load.</p>
</div>
<!-- this loads the calendar -->
<script type="text/javascript">
var maxdate=new Date("11/01/2011");
var mindate=new Date("08/01/2010");
loadTodaysCalendar(mindate,maxdate,"church_calendar");
</script>
You should have a directory on your server called calendar and The Calendar Html should be in the same directory as the page that you want it to appear on.
