sorry for not getting it but how am i supposed to fix this? i removed the blue set but still it got the rest of the errors
I gave you the image of what you should do.
Here it again:
Do this connections and remove the crossed node

i removed the crossed node but the connection is not happening, just in case is the set name the one from enemy or from the button widget?
and it seems in either case it just doesn’t connect with add child
the set name is from the button widget
click and hold on the result pin and then stop holding the button, it will appear all the nodes you can use, search for the “set name” node.
