SQL 2005 SPROC over Linked server

I'm trying to create a SPROC that includes a view over a linked server and am receiving an error.

Msg 2715, Level 16, State 3, Procedure usr_PacklistDetailintl_MU, Line 2
Column, parameter, or variable #1: Cannot find data type Order_ID.
Parameter or variable '@Order_ID' has an invalid data type.
Msg 2715, Level 16, State 3, Procedure usr_PacklistDetailintl_MU, Line 2
Column, parameter, or variable #2: Cannot find data type MU_ID.
Parameter or variable '@MU_ID' has an invalid data type.

The SPROC is below




create PROCEDURE [dbo].[usr_PacklistDetailintl_MU] @Order_ID Order_ID
, @MU_ID MU_ID AS
