Question : How to resolve the SQL error: "ORDER BY items must appear in the select list if the statement contains a UNION, INTERSECT or EXCEPT operator"?

Do you know how I can resolve the following error in the stored procedure that follows:
I created an Access application with Access as the front end and SQL Server 2005 as the back end database.

Msg 104, Level 16, State 1, Procedure procSpLN, Line 17
ORDER BY items must appear in the select list if the statement contains a UNION, INTERSECT or EXCEPT operator.
Msg 104, Level 16, State 1, Procedure procSpLN, Line 18
ORDER BY items must appear in the select list if the statement contains a UNION, INTERSECT or EXCEPT operator.
