select selection, (resi 26+57+70 in chain a) and (resi 12 in chain d)
^^^
You want 'or' not 'and'. (Think of a Venn diagram - with 'and' you are
looking for residues which are in both chain a and chain d, which is
impossible)

Hello,
I try to select several residues in several chains.
I tried something like that :
select selection, (resi 26+57+70 in chain a) and (resi 12 in chain d)
but it fails.
How can I Do ?
thanks
