Class is not defined error (and "is not a constructor error" too) when trying to implement Vista-like Ajax calendar (v2)

I am trying to implement the calendar from http://dev.base86.com/scripts/vista-like_ajax_calendar_version_2.html, and I included all of the javascript files, php files, and have mootools already successfully running. When I try to create the object (?) I get an error. The code I am using is attached.

Please let me know if you see where the problem is, or where to fix it. I did not change any of the code that I downloaded from the calendar website.

Thanks.
in events.php page: echo "<script>addLoadEvent(createCalendar);</script>";
 
and in my javascript function page:
 
function addLoadEvent(func) {
  var oldonload = window.onload;
  if (typeof window.onload != 'function') {
    window.onload = func;
  } else {
    window.onload = function() {
      oldonload();
      func();
    }
  }
}
function createCalendar()
{
	new vlaDatePicker('exampleI', {offset: { y: -2, x: 2 }, format: 'm/d/y'} );
	new vlaCalendar('block-element-id', {filepath:'calendar/'});
}

try importing the calendar last. Instead of:
<script type='text/javascript' src='/calendar.js'></script>
<script type='text/javascript' src='/mootools.js'></script>
<script type='text/javascript' src='/mootoolsMore.js'></script>
<script type='text/javascript' src='/functions.js'></script>
 
try:
<script type='text/javascript' src='/mootools.js'></script>
<script type='text/javascript' src='/mootoolsMore.js'></script>
<script type='text/javascript' src='/functions.js'></script>
<script type='text/javascript' src='/calendar.js'></script>
 
OR:
<script type='text/javascript' src='/mootools.js'></script>
<script type='text/javascript' src='/mootoolsMore.js'></script>
<script type='text/javascript' src='/calendar.js'></script>
<script type='text/javascript' src='/functions.js'></script>
