       if( syseUnitList!=null && syseUnitList.size()>0 ){
	for(int i = 0 ; i < syseUnitList.size() ; i++){	
								 Map appAreaA = (HashMap)syseUnitList.get(i);
      %>
      <td height="22" align="left"><input type="checkbox"  /></td>
      <%		
           if((i+1)%5==0){
             out.print("</tr><tr>");
	  }
