What group did you select from the list offered when you ran the script? Did it include all of your molecules, minus water? Or did you just select something like "Protein"?
You need to run make_ndx and general a group that contains all of the molecules you want. So you will want to do something like "1 | 2 | 3" when running make_ndx What those numbers are depends on what is contained within the gro file you feed it.
