How to track multiple user actions through UTM tags in GA?

Question

Google Analytics

Good day to all, tell me how to properly view user actions on the site through GA.
There are several sources of traffic to landingos, all transition buttons have utm tags. The landing page has a subscription form with a Submit button. Actually, how to filter out those users who came, say, from the FB source and clicked on the form button?
I can put anything on the button if you want.
How to see just transitions by utm tags is clear, but how to immediately double action - the transition from the source AND the click on the button was not found in the filters.

Answer 1

Hang up on the button the transfer of events in Google Analytics. In the reports, create a segment, where in the Traffic Sources you specify the required source, in the Advanced Conditions find the Event Action and select the event that you assigned to the button.
