Can't create array of splines

Thank you for your answer.

Forgive me but I am a 3D artist and not a programmer. So I don’t understad anything about blueprint although I trying continuosly to read guide and follow tutorial.

Now in my logic when I call the function “get all actor of class” I would get all the splines I have in the scene and storing that into an array ( path array), marke It as Instance editable and see all avaiable splines in the detail Tab. Then getting one of that and set it into a variable (Active Path) that is used from the actor. When it’ necessary with function “get (a Copy)” and instead of 0 I set 1 or 2 or 3… It sets the other splines stored rispectively in position 1 or 2 or 3… and sets into the Active Path variable.
