Trigger And Text Data Type

Hi All,
I have the code below on Sql 2k table with the column Descriptivetext defined as
Text Data Type. The table has Path and Page as the PK
I need to set a trigger to update Desciptivetext in other rows with the same path
when a one of them chnages.
Whenever I run the code, no row is updated

CREATE TABLE [dbo].[AB] (
[PATH] [varchar] (255) NOT NULL PRIMARY KEY CLUSTERED ,
[PAGE] [varchar] (60) NOT NULL PRIMARY KEY CLUSTERED ,
[DESCRIPTIVETEXT] [text] NULL
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
GO

CREATE TRIGGER [Update_Staging_Test] ON [dbo].[AB]
INSTEAD OF UPDATE
AS

Declare @TextPointer as Varbinary (16), @NewTextPointer as Varbinary (16), @Path
varchar(255), @Page as varchar(60), @DescriptiveText as varchar(7000)
If Update(DescriptiveText)
--Get the Path of the record from Inserted
Select @Page = Page, @Path = Path , @DescriptiveText = Cast(DescriptiveText as
Varchar(7000))
from Inserted


UPDATEAB
SETDescriptiveText = Cast (@DescriptiveText as Text)
WHEREPath = @Path
