Error converting data type varchar to numeric in my SQL Server stored procedure-CodePudding

I wrote this stored procedure and tried to retrieve data. But I get this error:

Msg 8114, Level 16, State 5, Procedure spMobileOperationsNew, Line 0 [Batch Start Line 0]
Error converting data type varchar to numeric.

Can you help me to fix this issue?

When I execute this line

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

I get the error shown above.
