Create Related Products [Solved]

after a long time working with hikashop it seems that i´m losing my knowledge. i cant remember the steps to create a related product module under the product page.
I created a new module in joomla with the name related products hikashop content, the i choose in system display under the main this module, and i don´t know what i did but it shows all the products not the one i choose like related.

Sorry i forgot to select related product in the module.
