Sigo recibiendo este TypeError y no sé por qué exactamente o cómo solucionar el problema. Todo parece estar bien, pero aún así, no muestra el HTML.

Está diciendo que hotelName.textContent = hotel.name; es nulo y no un objeto.

 (function() { var hotel = { name: 'Park', roomRate: 230, discount: 15, offerPrice: function() { var offerRate = this.roomRate * ((100 - this.discount) / 100); return offerRate; } } var hotelName, roomRate, specialRate; // Declare Variables hotelName = document.getElementById('hotelName'); // Get elements roomRate = document.getElementById('roomRate'); specialRate = document.getElementById('specialRate'); hotelName.textContent = hotel.name; // write hotel name roomRate.textContent = '$' + hotel.roomRate.toFixed(2); // write room rate specialRate.textContent = '$' + hotel.offerPrice(); // write offer price // Part Two: Calculate and write out the expiry details for the offer var expiryMsg; // The messaged displayed to users var today; // Today's date var elEnds; // The message that shows the message about the offer ending function offerExpires(today) { // Declaring Variables within the function for local scope var weekFromToday, day, date, month, year, dayNames, monthNames; // Add 7 days time (added in milliseconds) weekFromToday = new Date(today.getTime() + 7 * 24 * 60 * 60 * 1000); // This is our expiration date // Creates an array of days/ months dayNames = ['Sunday','Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday']; monthNames = ['January', 'February', 'March', 'April', 'May','June','July', 'August', 'September', 'November', 'December']; // Collect the parts of the dates to show on the page day = dayNames[weekFromToday.getDay()]; // Gets day of the week date = weekFromToday.getDate(); month = monthNames[weekFromToday.getMonth()]; year = weekFromToday.getFullYear(); //Create the message expiryMsg = 'Offer expires next '; expiryMsg += day + '<br/>(' + date + '' + month + '' + year + ')'; return expiryMsg; } today = new Date(); // Puts today's date in a variable elEnds = document.getElementById('offerEnds'); // Get the offerEnds element elEnds.innerHTML = offerExpires(today); // add the expiry msg // Finish the immediate invoked function expression }());
