pin error

[gull]

I have a question for entering an atm number in a simulated atm. What happens is when i enter 1 to enter a pin number it fails on me three times. If I hit a 2 it does what it is supposed to. When I enter something other than a 1 or 2 it also does what it is supposed to.



int dataEntryScreen()
{
//Declare variables
string valid,
pin;
bool found = false;
int pinChoice,
i,
j = 3;
ifstream Input;
//Perform do\while loop to check for correct validation
do
{
//Display the output
cout << "\t\tData Entry Screen";
cout << endl << "1) Enter pin number";
cout << endl << "2) Exit the ATM";
cout << endl << "Please enter a selection: ";
cin >> pinChoice;
//add color to background of data entry screen
//add color to text of data entry screen
system ("Color 3c");
/*

while (pinChoice < 1 || pinChoice > 2)
{
//Enter a correct choice
cout << "Please reenter 1 or 2: ";
cin >> pinChoice;
//add color to error message
//add color to error message
system ("Color 3a");
}
//If statement if 2 is selected
if (pinChoice == 2)
{
//exit the atm and returning a value
return -1;
}
//end do\while loop
} while (pinChoice > 2 || pinChoice < 1);
