Error messages when trying to create table with foreign key

I have created a db structure in Workbench for my record collection and have exported the 'create table' code. Here are the first 2 tables. The second table won't import - I'm getting an errno: 150 error. Can you tell me what's causing it?

Thanks
Charles
