So then I realized that the primary key should be unique and added an auto-incrementing id column. Originally, I had the product ID as the primary key and somehow setup a working relationship but then I was running into problems since the product ID's had duplicates - they were duplicated in order to list the different locations. In this table, I have 3 columns - An auto-incrementing primary key, the product ID and the location. IE "index4" would put the product in the 4th table in the index. I also have a location table listing where on the website that product will go. I've have a product table listing products, with an auto-incrementing primary key.

The screenshot for the ‘products’ table is given below. In our case, we have defined ‘product_id’ and ‘category_id’ as primary keys in the ‘products’ and ‘category’ table respectively. You must have defined a primary key (or at least an indexed column) in the referred table which will work as the foreign key in the referring table.
