We need to know details: just saying that is "giving me several
errors" doesn't provide much for us to go on.

You can create the lib files with LEaP, but you also need to use
addAtomTypes{} when you want to load these in, and well as to define the
masses for force field parameters (etc.) of the new types in a frcmod
file. Forgetting the addAtomTypes step is a common (and understandable)
omission, but I'm really guessing here. Look at the leaprc files in
$AMBERHOME/dat/leap/cmd for examples of the syntax that is needed.
