Thread: Switch Menu help

I'm using a switch for an ATM machine program. Every time I select an option for my switch it just reprints the menu. Did I mess something up within the cases? I've also tried putting case '1': and so on which did not work either.

Code:

#include <stdio.h>


int main()
{
    int balance, pin, tempPin, choice, choice2, choice3=0;
    char ans;


    printf("Please enter a pin:\n");
    printf("The beginning number must not start with 0\n");
    scanf("%d", &tempPin);


    if(tempPin < 1000){
        printf("Invalid Pin");
        return 0;
        }


    printf("Would you like a receipt?\n");
    printf("y or Y -> Yes\n");
    printf("n or N-> No\n");
    scanf("%c\n", &ans);




    do{
    system("cls\n");
    printf("Choose from the following:\n");
    printf("1- Fast Cash\n");
    printf("2- Withdraw\n");
    printf("3- Deposit\n");
    printf("4- Check Balance\n");
    printf("5- Get Card Back\n");




	scanf("%c\n", &choice);
    switch (choice){
    case 1:
            printf("Fast Cash: Select from the following\n");
            printf("1-- $20.00      2-- $40.00\n");
            printf("3-- $80.00      4-- $100.00\n");
            scanf("%c", &choice2);
                switch(choice2){
                case '1':
                        balance-=20;
                case '2':
                        balance-=40;
                case '3':
                        balance-=80;
                case '4':
                        balance-=100;
                    }
            printf("1- Another Transaction  2- Get Card Back\n");
            scanf("%d\n", &choice3);
            if(choice3 == 2){
                printf("Please take your card.\n");
                break;
            }
    case 2:
            system("cls\n");
            int amtWithdraw;
            printf("Enter an amount (enter 0 to cancel):");
            scanf("%d", &amtWithdraw);
            balance-=amtWithdraw;
            printf("1- Another Transaction  2- Get Card Back\n");
            scanf("%d\n", &choice3);
            if(choice3 == 2){
                printf("Please take your card.\n");
                break;
            }
    case 3:
            system("cls\n");
            int amtDeposit;
            printf("Enter amount to deposit:");
            scanf("%d", amtDeposit);
            balance += amtDeposit;
            printf("1- Another Transaction  2- Get Card Back\n");
            scanf("%d\n", &choice3);
            if(choice3 == 2){
                printf("Please take your card.\n");
                break;
            }
    case 4:
            system("cls\n");
            printf("Your Balance is: $%d\n", balance);
            printf("1- Another Transaction  2- Get Card Back\n");
            scanf("%d\n", &choice3);
            if(choice3 == 2){
                printf("Please take your card.\n");
                break;
            }


    case 5:
            printf("Please take your card.\n");
            break;
        }
    }
    while(choice3 != 2);
	return (0);
