SQL Server 2014 :: Select On Linked Databases

I am trying to find out what records on in one DB and not the other. This SQL statement works find if the DBs are on the same Server. If I replace on the DBs with a linked DB (on another server) I get the following error.

SELECT *
FROM [LinkedServer].[DBonLinkedServer].[dbo].[Sales Price]
WHERE NOT EXISTS
(SELECT [LocalDB].[dbo].[Sales Price].*
FROM [LocalDB].[dbo].[Sales Price]
WHERE ([LocalDB].[dbo].[Sales Price].[Item No_] collate Latin1_General_CS_AS = [LinkedServer].[DBonLinkedServer].[dbo].[Sales Price].[Item No_]) AND
([LocalDB].[dbo].[Sales Price].[Unit of Measure Code] collate Latin1_General_CS_AS = [LinkedServer].[DBonLinkedServer].[dbo].[Sales Price].[Unit of Measure Code]) )

Msg 4104, Level 16, State 1, Line 3
The multi-part identifier "LinkedServer.DBonLinkedServer.dbo.Sales Price.Item No_" could not be bound.

Msg 4104, Level 16, State 1, Line 4
The multi-part identifier "LinkedServer.DBonLinkedServer.dbo.Sales Price.Unit of Measure Code" could not be bound.
