Blueprint keeps asking for reference to c++ class

Hi,
i try to get variable from blueprint to c++. I follow this
[tutorial][1]

UPROPERTY(EditAnywhere, BlueprintReadWrite, Category = IPAddresReceive)
		int IPAddresReceive1;


then i try to create function that takes parameter from blueprint and call it from there.

UFUNCTION(BlueprintCallable)
		void Ip1Text(FString ip1);


But the same problem occurs in both.

I had similar problem.
Try making both your function and property static. Then you won’t need reference to the class.
