Tell us what’s happening:

function getCaloriesFromInputs(list) {
let calories = 0;

for (const item of list) {
const currVal = cleanInputString(item.value);
const invalidInputMatch = isInvalidInput(currVal);

if (invalidInputMatch) {

alert("Invalid Input:${invalidInputMatch} ");
}
}
}

Add Template literal within the alert () parentheses. Then "Invalid input: " ${invalidInputMatch} between the template literal. Finally you need the first value of invalidInputMatch array [].
