Hi,
I need an help about a problem with grouping dataset.
The code:
Dim fogli = From element In dati _
Group element By serial = CType(element, XXXXX).Week,
_
conc = CType(element, XXXXX).General Into
Group _
Select Group

With this code I group for week and then for General.. and until here
is all ok.. it does what I need.
How can I can't to get a third level on an items inside Gneral??

Thanks in advance for your help!

Cheers,
