# Page 116 - Looping with the do statement
> Thanks to Norbert Duenki who raised this issue by email on 4 April 2023.
In Step 3, I wrote, "As an optional challenge, add statements so that the user can only make ten attempts before
an error message is displayed."
In my code solution in GitHub, I made a mistake in my logic so that if the user entered the correct password on their tenth attempt, it output the error message.
I have updated the logic to fix this issue, as well as to use variables to store the actual password and the maximum number of attempts, as shown in the following code:
```cs
// Looping with the do statement
string? actualPassword = "Pa$$w0rd";
string? password;
int maximumAttempts = 10;
int attempts = 0;
do
{
attempts++;
Write("Enter your password: ");
password = ReadLine();
}
while ((password != actualPassword) & (attempts < maximumAttempts));
if (password == actualPassword)
{
WriteLine("Correct!");
}
else
{
WriteLine("You have used {0} attempts! The password was {1}.",
arg0: maximumAttempts, arg1: actualPassword);
}
```
