点击部门报错 jsp页面有错 望解决

HTTP Status 500 - /jsp1/Department/list.jsp (line: 57, column: 88) Attribute vaule invalid for tag property according to TLD

   这是第57行 感觉是<s:property vaule="currPage-1"/>无效  

 <a href="${pageContext.request.contextPath}/department_findAll.action?currPage=<s:property vaule="currPage-1"/>">[上一页]</a>&nbsp;&nbsp;
