Help with searching something

I have a field on a user where its a list of users who the user follows

now I have another database for buyandsells
I wanna search this database for any pieces of data created by any of the users in the current users following list of users

This is pretty much your filter. I’m guessing your using a repeating group, so your data source will be your buysell data set, filtered-> created by- current user following list of users.
