# Check for empty values

As a general rule, if a value of a custom field is empty, its corresponding Metafield either does not exist or is an empty string.\
\
A test for that particular custom field will not return anything ("blank" in Liquid terms), which gives you a nice clean syntax for checking if a given field has a value:

```liquid
{% if product.metafields.accentuate.title %}
   <h1>{{ product.metafields.accentuate.title }}</h1> 
{% endif %}
```

If you need to show a default value in case nothing is assigned to a Metafield, you can use the ['default' Liquid filter:](https://shopify.dev/api/liquid/filters/additional-filters#default)

```liquid
<h1>{{ product.metafields.accentuate.title | default: 'Default title' }}</h1> 
```

#### Multi-language fields

For multi-language fields, where there can be a value for one language and no value for another, you will need to test if the content for a specific language is a blank string or not:

```liquid
{% if product.metafields.accentuate.message['en'] != blank %}
  <p>{{ product.metafields.accentuate.message['en'] }}</p>
{% endif %}
```

#### Repeatable fields

If you are testing to see if an element in a **repeatable** field has a value, you need to test if the element's value is  **either** an empty string **or** null, both of which can be tested via the length of the element's value:

```liquid
{% for ingredient in product.metafields.accentuate.ingredients %}
    {% if ingredient.size > 0 %}
     <p>{{ ingredient }}</p>
   {% endif %}
{% endfor %}
```

And, if you are testing to see if a **repeatable** field has **any elements at all**:

```liquid
{% if product.metafields.accentuate.ingredients.size == 0 %}
   <p>No ingredients have been added</p>
{% endif %} 
```

Please see [this article](https://shopify.dev/api/liquid/filters/array-filters#size) for details on using the size filter.
