pair_style gauss

Hi guys,

I need to have two pair_style (“pair_style lj/cut/coul/long” and “pair_style gauss”) in my script representing two different potentials.
It works properly with one pair style “pair_style lj/cut/coul/long” but as I added “pair_style gauss” , the following error appeared “KSpace style is incompatible with Pair style” . BTW I am using version 30Oct10 of Lammps.

Looking forward to hearing any help.
