Can't make function Blueprint callable

Direct copy and paste and still get error:
error LNK2019: unresolved external symbol "__declspec(dllimport) public: static class UBlueprint * __cdecl FKismetEditorUtilities::CreateBlueprint

I’ll start from scratch… again. Keep doing the exact same thing… and somehow I’m closer than when I started… but still not as close as when someone else does the exact same thing. -_-

Thanks. Will worry with it tomorrow.
