Forum OpenACS Q&A: (MYOPENACS.ACS_OBJECTS_OBJECT_TYPE_FK) violated

I'm not sure why (that's why I'm posting in hopes of a hint on where to look) but when I try to insert stuff into my Oracle database it halts and errors out with this message:

I understand that some foreign key is referencing something that 
doesn't exist. But I am not sure if it's going:
 OpenACS --> Me or 
Me --> OpenACS


Thanks in advance
