# Date requirement

{% hint style="success" %}
**Requirements:**

* You must embed app to activate app
* For those who display widget on Cart page: You only can choose block Checkout button on Cart page
* For those who display widget on Product page: You only can choose block Add to card button on Product page
  {% endhint %}

{% hint style="warning" %}
TROUBLESHOOTING:

* Normally, you can use Automatic Block to block checkout button or add-to-cart button if customers don't select a date
* However, if it doesn't work (especially for custom theme) you need to use Manual Block by filling in Checkout button or Add-to-cart button CSS selector.

**Be awared that:**

* If date is required for your business flow, **Buy it now button on product page is also disabled**&#x20;
* **Direct payment method (Paypal, Shopay,..) is also disabled**

**Disabling these button will help avoid bypassing case without selected date.**&#x20;
