Manually Make Many-to-Many Relationship

[banning]

OK now i need to know how to manually create a many-to-many relationship

i found this tutorial SugarCRM relationship but its only for a one-to-many relationship... when i change it to many-to-many it doesn't exactly come out the way i want it and throws and error.

Can anyone give me directions on how to manually create this or point me towards a good tutorial?
