Dear Tim Lillestolen and others MOLPRO users,
did you solve your problem?
Because I have the same now, and I can not see a bug (bugs) in my Z-matrix.

I am interested in FSO3 radical in its C3v symmery, however even if I tryed  it
for Cs or C1 symmetry I obtain the same error.
The inputs for all three geometries are below.

Thank you very very much for your help,
Tereza
