missing ) before statement

Javascript original code causing missing ) before error. after some modification using escaped character. Able to fix this issue. Following are the code

 var stringContent = m_infowindow;
     infoWindow.setContent("<div id=\"infowin-overlay\""
       +"<P align=\"right\"><small>[ <a href=\"#\" onclick=\"clearOverlays(\'" +m_title+ " \');\">Remove</a> ]</small></P>"
       +"<br />"
       +stringContent+"</div>");
