iframe issue

Hi all, having an iframe issue in an external HTML object. Anything wrong with the code below? The frame comes up just fine, but it just populates with "Loading...." and does not open the page. Thanks

iframesrc="http://procedures.lww.com/lnp/view.do?pId=363983&s=v&id=1214154" width="760" height="500" frameborder="1" marginheight="0" marginwidth="0">Loading.../iframe

It does have the <> at the beginning and end
