        END
        --SELECT @QuoteId As ID
    END
    ELSE IF (@Modify = 'Update')
    BEGIN
        UPDATE dbo.Quotes SET
        Quote = @Quote,
        QuoteLink = @QuoteLink,
        Published = @Published,
        PublishedDate = @PublishDate

        WHERE Title = @Title
        --SELECT '1' As ID

    END
    ELSE IF (@Modify = 'Delete')
    BEGIN
        DELETE FROM dbo.Quotes
        WHERE Title = @Title

        --SELECT '1' As ID
    END
END

please any one help me how should i update my records when i try to update i gets an error saying:

Procedure or function sp_ModifyQuotes has too many arguments specified.

but i guess i have passed all proper parameters.

The Modify parameter is in the INSERT/VALUES parts of your SP - basically they do not match.
