title: Shopify Custom Text box according to product collection
body: <p>Im trying to do a conditional where if a product is in collection "personal" it will show a text box. I have this in the product.liquid page but it does't seem to be working.</p>
  
  <pre><code>   {% if collection.title == 'personal' %}
              &lt;div&gt;                             
                &lt;p&gt;&lt;input type="text" id="letter" placeholder="Enter up to 6 Letters" name="properties[letter]" /&gt;&lt;/p&gt;
              &lt;/div&gt;
     {% endif %}
  </code></pre>
