I'm getting this error and don't know what the problem is...

```
package com.codegym.task.task01.task0132;
/*
Sum of the digits of a three-digit number
*/
public class Solution {
public static void main(String[] args) {
System.out.println(sumDigitsInNumber(546));
}
public static int sumDigitsInNumber(int number) {
int number1 = number % 10;
int number2 = number1 % 10;
int number3 = number2 % 10;
int sum = number1 + number2 + number3;
return sum;
//write your code here
}
}
```
