Related Data for Dynamic Module

I am trying to relate my recently created module to another dynamic module but it's not showing up in the drop down list for when you're adding a custom field. 

I followed the instructions found here: docs.sitefinity.com/add-a-related-data-custom-field but it's still not showing up. Any help? 

Hi Patricia,

Do you see the module under Content and are you able to create items? If you are in Multisite, please, check whether the module is used by the site - Manage Sites -> from the site you are using - Actions -> Configure modules.
Please, check whether there are any errors in the browser console or any failed requests.
