SEL ECT Sum(整改问题个数)  提示给定关键字不在字典中  麻烦老师看看，谢谢！

当前代码：【红色部分不弹值】

Dim e As RequestEventArgs = rq.e
Dim cmd As SQL Co mm and = rq.cmd
cmd.C omma ndT ext = "SEL ECT Sum(整改问题个数) From 整改问题 where 主表guid=\'"&e.Values("主表guid")&"\'"
msg(cmd.CommandText)
Dim Values = cmd.ExecuteValues
If Values.Count > 0 Then
 msg(Values("整改问题个数"))
cmd.CommandText = "UPD ATE {统计表} SET 督促整改问题= " & Values("整改问题个数") & " WHERE guid=\'"&e.Values("主表guid")&"\' "
msg(cmd.CommandText)
cmd.ExecuteNonQuery()
End if

运行提示错误：
