Executing the event of a Blueprint from another Blueprint

Hello

What I wanted to make was relatively simple. I have a custom event in a blueprint from an actor called “FinalStatistics”. WHich basically just updates the information in a table on the world

I have a ‘finish line’ which has a box trigger. I simply wanted to make it so that when you get to the finish line(BP_StopClock), it activates the custom event at BP_FinalStatistics. However, the custom event is not showing up under Get All Actors Of Class → For Each Loop → Array Element as shown in the picture.

I was hoping you could guide me on this.

Thanks
