Looks like your topology file (top_heav.lib) is invalid. The MASS lines should contain the integer atom type, the atom name, and the mass, e.g. MASS 15 CT3 12.011 defines the CT3 atom type, with a mass of 12.011 (carbon). Looks like you've added a new oxygen atom type, but have missed one of these fields, since Modeller thinks the mass is actually the atom name in the error message.
