Wrote the same code as shown in video still not working?

const secsPerMin = 60; const minPerHour = 40; const hourPerDay = 24; const dayPerWeek = 7; const weeksPerYear = 52;

const secsPerDay = secsPerMin * minPerHour * hourPerDay; document.write('There are ${secsPerDay} seconds in a day');

From what you have posted, it looks like you are using single quotes in you document.write function. You need to use backticks for template literals in JavaScript. Replace the single quotes with backticks. It's the key right above the tab key. You also have minPerHour = 40; So the answer won't be correct. Hope this helps.

The variable you want to display needs the backticks to be able to display the code properly.

${} is whats needed to be able to fully use template literals backtick feature. make sure to properly place the backticks.

The error is: document.write('There are ${secsPerDay} seconds in a day'); Should use backtick like: document.write(There are ${secsPerDay} seconds in a day);

Because the single quotation will make everything in that single quotation become string, but if you use the backtick ( ), you can bring the value of secsPerDay and put in the string.

I suppose you wanted to display the result of ${secsPerDay} on your page as html paragraph or heading.

  1. Make sure you linked your JavaScript file to your html with the <script> tags, inside <body> element of your page;
  2. Make sure you used " ` " instead of " ' " for template literal after document.write ;
  3. Make sure to use desired html tags before There are ${secsPerDay} seconds in a day .

Here is the working example: 

const secsPerMin = 60; 
const minPerHour = 40; 
const hourPerDay = 24; 
const dayPerWeek = 7; 
const weeksPerYear = 52;

const secsPerDay = secsPerMin * minPerHour * hourPerDay; 

document.write(`<h1>There are ${secsPerDay} seconds in a day.</h1>`);
