i made a widget but it is not appearing here is my player pawn’s bluiprint.
If this widget is a HUD by chance then all you need is a create widget node. Set it to whatever widget you wish…then drag a wire from the return value and type add to viewport and it’ll be put on your screen. 
and if it’s a component in the BP toggling it’s visibility may work.
Good luck!!
Thanks I got is working now!
