Why won't my UMG Widget show?

Some screenshots here to show my set up. I don’t get why my communication from my LEVEL BP to my UMG BP isn’t working…

  1. At outset of level, I create my “Game Messages” widget and add it to the viewport (the intention of the widget is to flash up messages during my football game alerting the player of how many yds they gained after a play)

  1. Next, I run some script in the level BP that essentially says “once it’s the end of the play, send a message to the “Game Messages” widget (via an event dispatcher created IN the “Game Messages” widget) that a message should appear reporting how many yards were gained or lost on the play.”

  1. Finally, I attempt to receive that message from within the “Game Messages” UMG blueprint in order to fire off (show) a message that reports yards gained or lost (in this case, lost)

In setting breakpoints to try and assess the problem, it seems that my “Give Yds Gained or Lost Report” event in the last screenshot (within the “Game Messages” UMG blueprint) NEVER fires. I’ve also attempted to use Blueprint Interfaces to fire off events in my UMG BP to make messages show. Nothing works.

What in the bloody hell am I doing wrong!?!?!
