How Do I Populate a Notes Field with Iterated or List Values?

How Do I Populate a Notes Field with Iterated or List Values?

I have two tables:
Locations
CustomerContacts (there are many customer contacts for each location)

In a third form, I would like to show all of the CustomerContacts in a "note" field once a Location is selected.

I understand how to use the for each and iterate through the CustomerContacts, but I cannot seem to get it to list, or show all of them.

How can I do this? Thanks!
