Hi Guys,

i have tried to use:

=t_fe[ID]+t_nw[ID]+t_hn[ID]
where ID is column name and t are tables.

Also tried to do:

=INDIRECT("t_hana[ID]")+INDIRECT("t_nw[ID]")
but still not working.
How can i solve the problem?

It is possible to union columns from different tables into validation list?

Best,
Jacek
