SQL Query returning only one record

I am attempting to run a simple SQL stored procedure query, but am getting only 1 record returned. Anyone know what the issue is?

Alter PROCEDURE spGetRecruiterList
AS
BEGIN
    SET NOCOUNT OFF;
    DECLARE @TitleID as int
    set @TitleID = (Select TitleID 开发者_开发问答from tblJobTitle where JobTitle = 'Recruiter')
    Print @TitleID

    Select p.PersonID, p.FirstName, p.MiddleName, p.LastName
    from tblPerson p
    INNER JOIN dbo.tblLinkTitleToPerson tp 
    ON p.PersonID = tp.PersonID 
    WHERE tp.PersonID = @TitleID
    Order By p.LastName
END
GO

 WHERE tp.PersonID = @TitleID

Should be

 WHERE tp.TitleID = @TitleID

(probably!)
