Advanced Parameter Tutorial, Lesson 5, Multipart Identifier Error

Hello,

Hope I'm asking this question in the correct forum.

I'm a newbie in Reporting Services and currently working my way through the tutorials with AdventureWorks. Came across this error while doing the MSDN tutorial for Advanced Features, lesson 5 - user defined functions.

http://msdn2.microsoft.com/en-us/library/aa337435.aspx

Created a new report, copied the following to the query screen:

SELECT udf.ContactID, udf.FirstName + N' ' + udf.LastName AS Name,
c.Phone, c.EmailAddress, udf.JobTitle, udf.ContactType
FROM ufnGetContactInformation(@ContactID) udf
JOIN Person.Contact c ON ufn.ContactID = c.ContactID

I'm following the directions to the letter, and consistently get the following error:

"The multi-part identifier "ufn.ContactID" could not be bound."

"The multip-part identifier "ufn.ContactID" could not be bound. (Microsoft SQL Server, Error: 4104)"

I'm running SQL 2005 Enterprise on Windows XP.

Any help you can give will be much appreciated! Thank you.
