Ok I find a way to resolve my problem.
In Xpression, in my textfield, on Data Source, I fill only [I]Datalinq[/I], nothing in [I]Column, row[/I] ...
Like this I don't use for increment.
dim team as xptextobject
self.getobjectbyname("team",team)
dim seq as sequencer
seq=engine.sequencer
dim bti as xpbasetakeitem
seq.getFocusedTakeItem(bti)
dim idx as integer = bti.ID - 100 'because in my sequencer the ids are from 101 to 110
dim dl as xpdatalinq
dl=team.datalinq
dl.column="TVMatch\team\name"
I put this script on tabs OnPrepare, OnPreviewRender, OnOnline.
And know I have the good preview in Xpression and Dashboard
