I believe something has gone wrong after following step 40 of 42. Once I had finished writing the handlebars template the next step was to delete the html code as the handlebars code would provide the information. But once I deleted the html code and refreshed the page everything disappeared and I can’t seem to find where I went wrong in the handlebars code for it not to show up. Below is my main.js code and my store.html code. If anyone can help it would be really appreciated.

main.js -

const context = {

body: ‘Musicon is a budding musical storefront with a mission to share the joy of music. These magnificent auditory tools are designed with musical creators, like you, in mind.

Hello David,

Can I kindly see your code from instruction 35 to 39 (the handlebars code)?.. Am thinking that’s where the problem might be.

Hello! Thank you for the reply, please see the code for steps 35-39 below.

{{#each instrument}}
    <article class="instrument">
      <img class="image" src="{{this.image}}" alt="{{this.name}}">
      <section class="details">
        <h2 class="name">{{this.name}}</h2>
        <p class="description">{{this.description}}</p>
        {{#if sale}}
        <p class="price"><del>{{this.price}}</del></p>
        <p class="sale">{{this.sale}}</p>
        {{else}}
        <p class="price">{{this.price}}</p>
        {{/if}}
      </section>
    </article>
{{/each}}

Hey David,

Sorry I have taken a while. I found the problem though.

So your class name in your element is “instrument” instead of “instruments”. I believe after you change this, your code will work just fine :slightly_smiling_face:

It should look like this:

<article class="instruments">

Oh and in the paragraph elements with class “price”…add Price: before the handbar expression so it looks like this:

<p class="price"><del>Price: {{this.price}}</del></p>

and in the else block:

<p class="price">Price: {{this.price}}</p>

Hope this helps! :slightly_smiling_face:

Relatively old topic but for future reference in case any one else gets stuck, the issue is to do with this line:

{{#each instrument}}

This needs to match up with the property array, in this case the property is instruments

const context = {
title: ‘Welcome to Musicon’,
body: ‘[...]’,
instruments: [
...

So the handlebars code would be {{each instruments}}

#9

Me neither. Did you find a solution in the end?
