SQL syntax error , Incorrect Syntax?

Every time I run the query I get the syntax error. The thing is when I run the lines where the error is supposedly occurring the code runs that section so I don't know why I'm getting the below error messages.

Msg 102, Level 15, State 1, Line 1  
Incorrect syntax near ')'.  
Msg 102, Level 15, State 1, Line 1  
Incorrect syntax near ')'.

My code:

declare @Source_Database_Name AS varchar(255) = 'dbo.Production2';

declare @Company_Id int = 1 --declare a companyid

    processorder int,
    tablename NVARCHAR(100)
    )
