Tell us what’s happening:

Your span should have the class attribute set to surplusOrDeficit.toLowerCase().

Your code so far

<!-- file: index.html -->


/* file: styles.css */


/* file: script.js */
// User Editable Region

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';
  output.innerHTML = `<span class=${surplusOrDeficit.toLowerCase()}></span>`;
}

Your class attribute should be a string.

i understand but do not still get the place of the string

Hey,
Can you share your updated code?

Okay. When you add an attribute to an element, the syntax is class="someclass" but you have class=someclass. Is that clearer?
