Tell us what’s happening:

You should access the innerHTML property of the output element.

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';
  const output.innerHTML = ``;
}

It is not accepting my

const output.innerHTML = ``;

Instead of making a new variable called output they wanted you to update the existing output variable (which was declared earlier)

the instructions say

Step 81

You need to construct the HTML string that will be displayed in the output element. Start by assigning an empty template literal to the innerHTML property of the output element on a new line at the end of the function.

then I enter

const output.innerHTML = ``;

and Im getting error

You should access the innerHTML property of the output element.
