To me, it seems that your syntax for chain and residue definitions is incorrect.
See the 'Tutorial' section on the CNS website, which gives some very nice examples.
For example, if you want to select chain K and residues 2 and 15, chain L and residues 1, 2, and
14, and so on, here's pne possible syntax:
((segid K and resid 12) or (segid K and resid 15) or (segid L and resid 1) or (segid L and resid
2)....blah blah)
Make sure to keep track of the opening and closing parentheses.
Hope that helps.
