Having problems with the goToCheckout method at the bottom.
I am getting this error:

java.lang.NullPointerException
	at Member.goToCheckout(Member.java:86)

I know name has got a value because when i inspect the object the names has my name in there.
The payment must have a value because you have to type an amount in.
Can anyone help me out here.

public class Member
{
    // instance variables
    private String name;
    private String id;
    private String pinNumber;
    private Store store;
    private Item item;
    private int money;

    /**
     * Constructor for objects of class Member
     */
    public Member(String newName, String newId, String newPinNumber, Store store)
    { 
        if(newId.length() <= 10)
        {
            name = newName;
            id = newId;
            
            if(newPinNumber.length() == 4)
            {
                pinNumber = newPinNumber;
            }
            else
            {
                pinNumber = "0";
                System.out.println("Your pin number must be 4 characters");
            }
        }
        else
        {
            name = newName;
            id = null;
            pinNumber = newPinNumber;
            money = 500;
            System.out.println("Your ID must be less than 10 characters");
        }
    }
