Can anyone tell me why my .forEach is failing?

I tried using a .forEach instead of a for loop - can anyone see what's wrong with my code?

function calculate_gpa(student_grades){
  const grade_total = 0;
  const number_of_grades = student_grades.length;
  student_grades.forEach((element) => {
    if(element < 1 || element > 4){
      console.log("Invalid grade: " + element);
      return "Can't complete calculation.";
    } else {
      grade_total += student_grades[i];
    }
  });
  const gpa = grade_total / number_of_grades;
  return gpa;
}
const reggie_grades = [4, 4, 3, 4];
const dave_grades = [1, 2, 3, 2];
console.log(calculate_gpa(reggie_grades));
console.log(calculate_gpa(dave_grades));

In first glance ur using a forEach loop. You can't access elements in the array with a [] when ur using forEach loop. The forEach() method calls a function once for each element in an array, in order

 grade_total += student_grades[i];

It should be:

 grade_total += element;
