Tell us what’s happening:

Ok, this is the request:
Declare a budgetCalories variable and set it to the result of calling getCaloriesFromInputs – pass an array containing your budgetNumberInput as the argument.

And I get this hint for the code below:
You should call getCaloriesFromInputs with [budgetNumberInput] as the argument

Your code so far

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(budgetNumberInputs);
const budgetCalories = getCaloriesFromInputs([budgetNumberInputs]);

}

first delete the copy of the variable you made
then remove the last s from budgetNumberInput and it will work, like this:

const budgetCalories = getCaloriesFromInputs([budgetNumberInput]);

happy coding.

Hi my friend
remenber he told us A NodeList is an array-like and budgetNumberInput variable. However, you used getElementById , which returns an Element , not a NodeList .whereby we have to send an array with the element budgetNumberInput inside [budgetNumberInput]

const budgetCalories = getCaloriesFromInputs([budgetNumberInput]);
this worked for me

greetings
