Help With INSERT TRIGGER - Fails With Error.

I need a trigger (well, I don't *need* one, but it would be optimal!)
but I can't get it to work because it references ntext fields.

Is there any alternative? I could write it in laborious code in the
application, but I'd rather not!

DDL for table and trigger below.

TIA

if exists (select * from dbo.sysobjects where id =
object_id(N'[dbo].[tblMyTable]') and OBJECTPROPERTY(id, N'IsUserTable')
