I am trying to forward engineer my new schema onto my db server, but I can't figure out why I am getting this error. I've tried to search for the answer here, but everything I've found has said to either set the db engine to Innodb or to make sure the keys I'm trying to use as a foreign key are primary keys in their own tables. I have done both of these things, if I'm not mistaken. Any other help you guys could offer?

Here is the SQL for the parent tables.
