SQLRegionID
SQLLastUpdated
SQLIPAddress
SQLEmployeeID

I do not use these fields in the form I have created.  The trigger code follows:

CREATE TRIGGER trgInsUpdOffClass ON dbo.OffClass
FOR INSERT, UPDATE
AS
UPDATE OffClass
SET SQLLastUpdated = GetDate(),
SQLEmployeeID = dbo.fnGetContextLogin(),
SQLIPAddress = dbo.fnGetMACAddress()
FROM Inserted i
WHERE i.SQLGUID = OffClass.SQLGUID

The SQLLastUpdated column is causing the collision.

Ideas?
