# Adding Quantity Field to a Product Card

When a customer clicks on a base product that has a per unit, tiered, or volume pricing model, a field should be displayed for them to enter the quantity they wish to subscribe to.

Below is the code that can be used:

```html
< div class="qty-container" data-bind="visible: selected()">

<input type="text" class="input-spinner" min="1" data-bind="value: quantity">

</div>
```

This is in combination with the button code:

```html
<button class="btn btn-primary" data-bind="click: select">SELECT</button>
```
