在我的 SQL Server 存儲過程中將數據類型 varchar 轉換為數字時出錯

我寫了這個存儲過程並試圖檢索數據。 但我收到此錯誤：

將數據類型 varchar 轉換為數字時出錯。

你能幫我解決這個問題嗎？

ALTER PROCEDURE [dbo].[spMobileOperationsNew]

        SELECT

            tt.[ActDiscVal], tt.[FinalDiscBudget]
        FROM
            TerritoryWiseTradeDiscount AS tt
        WHERE 
            tt.[TerCode] = @territorycode 
            AND tt.[Year] = @disYear 
            AND tt.[Month] = @disMonth
    END
END

當我執行這一行

EXEC [dbo].[spMobileOperationsNew]'Get_TerritoryWiseTradeDiscount','KEG',2021,'November'

我收到上面顯示的錯誤。
