WorkAround Explorer issue, page breaks when I import from salaryData.js

This is the exercise I’m working on. I’m on step 4.

I’ve looked at other posts in the forum and of their issues seem to be caused by minor syntax errors, misspellings, or the wrong address to the module being imported from. I’ve quadruple checked my code and I don’t see any issues. Yet, when I import from salaryData.js, the page completely changes. It removes two columns and I see no radio buttons.

Here is salaryData.js:

const salaryData = [
  { role: 'CTO', company: 'Big Data Inc.', salary: 320000},
  { role: 'Technical Lead', company: 'Big Data Inc.', salary: 230000},
  { role: 'Software Engineer II', company: 'Big Data Inc.', salary: 180000},
  { role: 'Software Engineer I', company: 'Big Data Inc.', salary: 140000},
  { role: 'CTO', company: 'Medium Data Inc.', salary: 215000},
  { role: 'Technical Lead', company: 'Medium Data Inc.', salary: 165000},
  { role: 'Software Engineer II', company: 'Medium Data Inc.', salary: 140000},
  { role: 'Software Engineer I', company: 'Medium Data Inc.', salary: 115000},
  { role: 'CTO', company: 'Small Data Inc.', salary: 175000},
  { role: 'Technical Lead', company: 'Small Data Inc.', salary: 135000},
  { role: 'Software Engineer II', company: 'Small Data Inc.', salary: 115000},
  { role: 'Software Engineer I', company: 'Small Data Inc.', salary: 95000},

const getRoles = () => {
  return ['CTO', 'Technical Lead', 'Software Engineer II', 'Software Engineer I'];

const getCompanies = () => {
  return ['Big Data Inc.', 'Medium Data Inc.', 'Small Data Inc.'];

const getDataByRole = role => {
  return salaryData.filter(obj => obj.role === role);

const getDataByCompany = company => {
  return salaryData.filter(obj => === company);

export {getRoles, getCompanies, getDataByRole, getDataByComapany};
export default salaryData;


// TODO: Add your import statements here.
import {getRoles, getCompanies} from './modules/salaryData.js';
// TODO: Get the companies and roles using the salaryData module.
const companies = getRoles();
const roles = getCompanies();

// Create input buttons for every company and role represented in the data.
renderInputButtons(companies, 'company');
renderInputButtons(roles, 'role');

// This function will create a new <section> with radio
// inputs based on the data provided in the labels array.
function renderInputButtons(labels, groupName) {
  const container = document.createElement('section');
  container.setAttribute('id', `${groupName}Inputs`);

  let header = document.createElement('h3');
  header.innerText = `Select a ${groupName}`;

  labelas.forEach(label => { // For each label...
    // Create the radio input element.
    let divElement = document.createElement('div');
    divElement.setAttribute('class', 'option');

    let inputElement = document.createElement('input');
    inputElement.setAttribute('type', 'radio');
    inputElement.setAttribute('name', groupName);
    inputElement.setAttribute('value', label);

    // Create a label for that radio input element.
    let labelElement = document.createElement('label');
    labelElement.setAttribute('for', label);
    labelElement.innerText = label;

    // Update the results when the input is selected.
    inputElement.addEventListener('click', updateResults);



function updateResults(){
  // Get the current selected company and role from the radio button inputs.
  const company = document.querySelector("input[name='company']:checked").value;
  const role = document.querySelector("input[name='role']:checked").value;

  // If either the company or role is unselected, return.
  if (!company || !role) { return; }

  // TODO: Use the workAroundModule functions to calculate the needed data.
  const averageSalaryByRole = 0;
  const averageSalaryByCompany = 0;
  const salary = 0;
  const industryAverageSalary = 0;

  // Render them to the screen.
  document.getElementById('salarySelected').innerText = `The salary for ${role}s at ${company} is \$${salary}`;
  document.getElementById('salaryAverageByRole').innerText = `The industry average salary for ${role} positions is \$${averageSalaryByRole}`;
  document.getElementById('salaryAverageByCompany').innerText = `The average salary at ${company} is \$${averageSalaryByCompany}`;
  document.getElementById('salaryAverageIndustry').innerText = `The average salary in the Tech industry is \$${industryAverageSalary}`;

Am I just overlooking something simple?

I have literally no idea what fixed it. I reset the exercise many times and carefully did the same thing over and over again. Eventually, it just worked.
