学做筛选提示错误解

在应使用条件的上下文(在 '初中2016级3班' 附近)中指定了非布尔类型的表达式。   请问老师上什么原因

老师，查到了，谢谢

If e.GetValues.ContainsKey("unfilter") Then
    wb.ClearCookie() '清除Cookie
Else
    Filter =  Functions.Execute("GetFilter",e,wb)'合成条件表达式
End If

取消筛选清除的cookie 点list的下一页就反回到登录了呢

Dim e As RequestEventArgs = args(0)
'保存订单
Dim  wb As New weui
Dim dr1 As DataRow = DataTables("用户").sqlfind("身份证号 = '" & e.Cookies("username") & "'")
Dim dr As DataRow = DataTables("学生信息").SQLFind("[_Identify] = " &  e.GetValues("oid"))
If ValidPIN(e.postvalues("身份证号"))= False
    With wb.AddMsgPage("","msgpage","注册失败", "身份证号不正确或不规范")
        .icon = "Warn" '改变图标
        .AddButton("btn1","返回").Attribute = ""
    End With
   e.WriteString(wb.Build)
 '   Return() '必须返回
End If

Dim nms() As String =  {"身份证件号","学生姓名","学籍号","联系电话","民族","政治面貌","户口性质","家庭住址","健康状况","状态"}
For Each nm As String In nms
    If e.PostValues.ContainsKey(nm) Then
        dr(nm)= e.PostValues(nm)
    End  If
Next
dr.Save()

老师，我想判断下身份证是否标准，这样调用目标错误
