can anyone tell me what is wrong with this code?

function calculateCalories(e) {
  e.preventDefault();
  isError = false;

  const breakfastNumberInputs = document.querySelectorAll('#breakfast input[type=number]');
  const lunchNumberInputs = document.querySelectorAll('#lunch input[type=number]');
  const dinnerNumberInputs = document.querySelectorAll('#dinner input[type=number]');
  const snacksNumberInputs = document.querySelectorAll('#snacks input[type=number]');
  const exerciseNumberInputs = document.querySelectorAll('#exercise input[type=number]');

  const breakfastCalories = getCaloriesFromInputs(breakfastNumberInputs);
  const lunchCalories = getCaloriesFromInputs(lunchNumberInputs);
  const dinnerCalories = getCaloriesFromInputs(dinnerNumberInputs);
  const snacksCalories = getCaloriesFromInputs(snacksNumberInputs);
  const exerciseCalories = getCaloriesFromInputs(exerciseNumberInputs);
  const budgetCalories = getCaloriesFromInputs([budgetNumberInput]);

  if (isError) {
    return;
  }

  const consumedCalories = breakfastCalories + lunchCalories + dinnerCalories + snacksCalories;
  const remainingCalories = budgetCalories - consumedCalories + exerciseCalories;
  const surplusOrDeficit = remainingCalories >= 0 ? "Surplus" : "Deficit";
}

Hello!

You have the wrong operatorhere:

Try making it a less-then sign: < as you are checking if it is less than the number.

3

i’ve tried putting in -= or <= but neither of them works

4

You only need a < you don’t need the equals to sign there as well.
