[RESOLVED] Linked List - Addng entry at the end

[Cpp_Noob]

i have a Node and i want to add a new entry at the end
the first entry is added correctly on head but the next entry is not added at all

struct Node
{
	FlightRec entry;
	Node *next;
};
class List 
{
public:
	void ReadFlight();
	void AddFlight(FlightRec iInput);

private:
	Node *head;
};


void List::AddFlight(FlightRec iInput)
{
	Node* New_Node = new Node;
	New_Node->entry = iInput;
	New_Node->next = NULL;

	if (head == NULL)
	{
		head = New_Node;
		head->next = NULL;
	}
	else
	{
		Node* previous = head, *current = head->next ;

		while(current != NULL)
		{
			previous = current;
			current = current->next;
		}

current = New_Node;
// head->next = New_Node;
current->next = NULL;

bool breakpoint = false;
	}

}

when i use head->next = New_Node; it adds the new entry but not if i use the current pointer
any ideas why??

thanks
