What is wrong in this code related to pointer

/* The structure of the Linked list Node is as follows:

struct Node
{
    int val;
    struct Node *next;

    Node(int data){
        val = data;
        next = NULL;
    }

}; 
*/

void intersection(Node **head1, Node **head2,Node **head3)
{

    cout<<*head1->val;
}

The above code in not working but when I take another pointer Node* h1=*head1; and then print its value its working fine. In both codes the value I want to print is same then why above code is wrong;

/* The structure of the Linked list Node is as follows:

struct Node
{
    int val;
    struct Node *next;

    Node(int data){
        val = data;
        next = NULL;
    }

};

void intersection(Node **head1, Node **head2,Node **head3)
{

    Node* h1=*head1;
    cout<<h1->val;
}
