window.open error unterminated string constant

I am trying to open a link in a new window and get this error. What am i doing wrong on the code below:

<a onclick="window.open('http://c1739202.cdn.cloudfiles.rackspacecloud.com/Assignments_final_demo.htm' 
width=" height='860,menubar=no,status=no,"' location="no,toolbar=no,scrollbars=no')&quot;" 
 c1739202.cdn.cloudfiles.rackspacecloud.com
 window.open(?http: 1155, Assignments_final_demo.htm?,?>
<img alt="" hspace="0" src="/files/images/PUdropBoxDemoButton.jpg" align="default" border="0" /></a></div>

I ended getting the window to open with no errors but now it opens not only the popup window but opens in the current window I am on. so it opens up twice. Does anyone have any ideas why it is doing this, here is my code:

<a onclick="window.open('http://c1739202.cdn.cloudfiles.rackspacecloud.com/Assignmnets_final_demo.htm');" 
href="http://c1739202.cdn.cloudfiles.rackspacecloud.com/Assignmnets_final_demo.htm"  ?><img alt="" hspace="0" src="/files/images/PUdropBoxDemoButton.jpg" 
align="default" border="0" /></a>
