A simple question about C ++ template inheritance

Question

template <class T>
class baseclass{
protected:
    T data;
public:
    baseclass(){};
    void setData(T d);
};

template<class T>
void baseclass<T>::setT(T d){
    data = d;
}

My base class shown above, one protected member variable, one setter.

template <class T>
class aclass : public baseclass<T>
{
    public:
        aclass(T d);
};

template<class T>
aclass<T>::aclass(T d){
     setData(d); <---WORKS
     data = d;   <---DOESN'T WORK
}

Now this is my subclass of the first. For some reason, accessing a protected member variable does not work directly, although I believe it should be. However, access to the setter is working fine. I am noob with C ++, I am sure that I am missing something obvious.
