Can't call custom event from another blueprint

Hello!
I’m new to UE and have been working for the second week. Now I’m creating an inventory system but I can’t understand howto call a custom event from another blueprint.
I have created a custom event (UpImage) but I can not call it from BP_ThirdPersonCharacter, the event I want to call doesn’t exist in search tab.

This is custom event I want to call

This is where I want to add it

you’re dragging from the execution pin. you must drag from the blue widget output circle :slight_smile:

Sorry, I attached the wrong second screen. I call the event from WidgetReference variable but it still can’t find the UpImage event from the list
