Products & Contacts

Products & Contacts

I'm a bit confused about how to link / associate Contacts with Products:
 

I added Products to my Tabs, and created a Test Product.

 

I can’t find any way however to associate a Contact with this? It shows me a section in the Product called “Contacts” and there’s an option “New”, but I want to associate existing Contacts with this.

 

How do I do this?

 

Also, some of our customers book multiple Tours (“Products”). Can a contact be associated with more than one Product?
