Check at the bottom of the description in this file. That’s an example. 
Hello,
i was reading the “9 Tips for Creating and Maximizing a Steady Income Stream by Selling Stock” and under “Tip 2 – Cross Sell” it says that it is important to link other items on a single item page. Well, i don’t know how to do that because when i upload the file all i have is one text field, nothing more.
Can anyone with more experience explain to me please the system behind this.
Thanks
