SSRS查询获取标量变量错误，而不是在Visual Studio中使用参数

Question

我在SSRS中使用报告中未使用已声明的参数时遇到麻烦。在报告中，我已经有两个查询，它们都使用@Period来确定用户请求的月份。但是，在第三份报告中，它不断出现标量变量错误，并希望我声明@Period，当然，除非我指定int值会带来完全不正确的数字，因为它是所有值的总和而不是设定的时间。

我已经遍历了代码，甚至从工作代码中复制了粘贴@Period的代码，以查看是否存在隐藏的空间或某些阻止其使用正确参数的东西，但仍然看不到它。下面是Visual Studio中报告数据窗口的屏幕截图以及我正在使用的代码。我只是不明白为什么它不能使用@Period。

Declare @Year As int
--Declare @Period As int  = 9

--Sets up the year for this financial year
If @Period Between 5 and 12
Begin
Set @Year = Year(Getdate()) + 1
End
Else 
Set @Year = YEAR(Getdate())
--Sets the Declared Period to the correct number for Clients
if @Period = 5 
Begin
Set @Period = 1
End
ELSE if @Period = 6
Begin
Set @Period = 2
End
Else if @Period = 7
Begin
Set @Period = 3
End
Else if @Period = 8 
Begin
Set @Period = 4
End
Else if @Period = 9
Begin
Set @Period = 5
End
Else if @Period = 10
Begin
Set @Period = 6
End
Else if @Period = 11
Begin
Set @Period = 7
End
Else if @Period = 12
Begin
Set @Period = 8
End
Else if @Period = 1
Begin
Set @Period = 9
End
Else if @Period = 2
Begin
Set @Period = 10
End
Else if @Period = 3
Begin
Set @Period = 11
End
Else
Set @Period = 12
