Subject: AMBER: huge bond distances in new residue

Hello,
   I'm trying to create a new residue (similar to tutorial 4). The
type of error message follows (from 'check RES' in tleap), but I have them
also
for the new atom type I'm defining. The C# and HC# are of type CT and HC so
it should
know about them without me redefining them in the frcmod. When I tried to
define a CT-CT-CT angle for example, I got the error 'Unknown keyword:
CT-CT-CT
in parameter file'.
   I load the frcmod file, the lib file, then the pdb file in that order
before I
get these errors. I am sourcing leaprc.ff99 to start with.
   
   What am I doing wrong?
