New Post: SPServices call not being recognized

Jacob,

I am trying to use SPServices in my list form (Calendar) for adding new event. My page is not able to recognize SPServices. Below is my code from some sample:
<!-- Reference jQuery on the Google CDN --><script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js" type="text/javascript"></script><!-- Reference SPServices on cdnjs (Cloudflare) --><script src="http://cdnjs.cloudflare.com/ajax/libs/jquery.SPServices/2013.02a/jquery.SPServices-2013.02a.min.js" type="text/javascript"></script>
<script type="text/javascript"> $(document).ready(function() { alert ("js on."); alert ('jQuery on.'); var thisSite = $().SPServices.SPGetCurrentSite(); alert ('Hello World! Your site is : ' + thisSite ); });</script> I do get first 2 alerts but not the SPervices one

Thanks
Snehal
