class members restricted after converting to template - c++

Question

So I'm working with templates and I've run into a problem. After I converted my code into templates I am no longer able to access the private members of my classes. I get the error that 'current' is a private member of 'Iterator'. So first I have each class:
template <class T>
struct nodeType {
T info;
nodeType<T> *link;
};
template <class T>
class Iterator {
public:
Iterator();
Iterator(nodeType<T> *);
T operator*();
bool IsNull();
Iterator<T> operator++();
Iterator<T> operator++(int);
bool operator==(const Iterator<T> &) const;
bool operator!=(const Iterator<T> &) const;
Iterator<T> &operator=(T);
private:
nodeType<T> *current;
};
template <class T>
class LinkedList {
public:
LinkedList();
LinkedList(const LinkedList<T> &);
~LinkedList();
void InsertHead(T);
Iterator<T> InsertAfter(T, Iterator<T>);
Iterator<T> Search(T);
bool IsEmpty();
void Print();
void DestroyList();
Iterator<T> Start();
Iterator<T> End();
const LinkedList<T> &operator=(const LinkedList<T> &);
private:
nodeType<T> *head;
};
Before I used templates I used the following code, but not current is private and this no longer works.
template <class T>
Iterator<T> LinkedList<T>::InsertAfter(T input, Iterator<T> marker) {
Iterator<T> newNode = new nodeType<T>;
Iterator<T> findNode = marker;
newNode = input;
newNode.current->link = findNode.current->link;
findNode.current->link = newNode.current;
return findNode;
}
Then I tried to do the following and It get no errors but when I called the InsertAfter function to add a new item to the list it doesn't show up. I did a cout newNode = input; and it shows the value I want to insert, but the nodes don;t seem to connect up. Why can't I use the previous code I was doing before? Like newNode.current->link = findNode.current->link;
template <class T>
Iterator<T> Iterator<T>::operator++() {
current = current->link;
return *this;
}
template <class T>
Iterator<T> Iterator<T>::operator++(int) {
Iterator<T> temp;
temp = *this;
++(*this);
return temp;
}
template <class T>
Iterator<T> LinkedList<T>::InsertAfter(T input, Iterator<T> marker) {
Iterator<T> newNode = new nodeType<T>;
Iterator<T> findNode = marker;
newNode = input;
newNode++ = findNode++;
findNode++ = newNode;
return findNode;
}

You can't do newNode.current within a member function of LinkedList, because current is private to Iterator. That's what private means - it is only accessible from member functions of the class it belongs in.
Clearly your "old" code was different. Possibly you had Iterator friend LinkedList in the old code. If you post your old code it might clear things up.
