Please see www.azre101.com  WHY is it showing  "Source: http://www.eventbrite.com/calendar-widget?eid=737950229/"

I embedded a widget/element on the Sidebar (Upcoming Events) using iframe (see below code) and it is showing the  "Source: http://www.eventbrite.com/calendar-widget?eid=737950229/"

Zoho Wiki striped the below code down to this only which being used in the Sidebar element:

<iframe frameborder='0' scrolling='auto' src='http://www.eventbrite.com/calendar-widget?eid=737950229'/>

FYI: the original code I paste in was:
<div style="width:195px; text-align:center;" ><iframe  src="http://www.eventbrite.com/calendar-widget?eid=737950229" frameborder="0" height="367" width="220" marginheight="0" marginwidth="0" scrolling="no" ></iframe><div style="font-family:Helvetica, Arial; font-size:10px; padding:5px 0 5px; margin:2px; width:195px; text-align:center;" ><a style="color:#ddd; text-decoration:none;" target="_blank" href="http://www.eventbrite.com/features?ref=ecal" >Sell Tickets Online</a><span style="color:#ddd;" > through </span><a style="color:#ddd; text-decoration:none;" target="_blank" href="http://www.eventbrite.com?ref=ecal" >Eventbrite</a></div></div>
