(BluePrint)Problem with calling Ref?

[BlackPanda22]

Hello I’m a bit new to this scene and would like to get some help regarding this issue,
I’m Having and error “Accesses None trying to read property Fighters2”
if i understand correctly this error its trying to call him but he doesn’t find it or doesn’t have access to it before he doesn’t find it or something is running before this code and it doesn’t work because it needs this code

but i don’t think i understand where i did it wrong, in the image you can see i do a cast to the BP i need in the begin play

i’m also having the same error in my level blue print where i set the camera location according to 2 players(Its a fighting game to be clear) not sure what im missing here.

Ok After some sniffing around the internet and a lot of videos I solved it with either “is Valid” or making the reference into a “is Valid”
