# Defining Gender and Date of Birth metafields

**Date-of-Birth** and **Gender** are pre-created custom fields in our app but their metafields are not defined by default, that is, they exist in Shopify but as **undefined** customer metafields. You may want to define them in order to, for example, [pin the metafields](https://help.shopify.com/en/manual/metafields/pinning-metafield-definitions) so you can quickly check the stored values per customer on the Shopify Customers dashboard. 

Defining these metafields is something pretty quick to do in the Shopify Admin and you just need to be careful to define the metafields with the right **content type** so there isn't any risk of malfunction in the app.

Go to your **Shopify admin > Settings > Metafields > Customers > Metafields without a definition** and find there our two undefined metafields for **Date-of-Birth** and **Gender**, which are named respectively: *froonze\_cp\_custom.date\_of\_birth* and *froonze\_cp\_custom.gender*

Click on the first of them, *froonze\_cp\_custom.date\_of\_birth*, fill the **Name** with any you want (e.g. *Date of birth*) and for **Content Type** choose **__Date__**. Don't choose any other content type. Then **Save**.

Now click on the second, *froonze\_cp\_custom.gender*, fill the **Name** with any you want (e.g. *Gender*) and for **Content Type** choose **__Single line text__**, don't choose any other content type. After that click on **Save** on the top right corner.

Lastly, you can check the result back in **Settings > Metafields > Customers** and pin the two (now defined) metafields, so they'll be showing as values in the individual customer information panels in the Customers Dashboard.
