Title: Validation error Last modified: August 30, 2016 --- # Validation error * Resolved [maxoud](https://wordpress.org/support/users/maxoud/) * (@maxoud) * [10 years, 11 months ago](https://wordpress.org/support/topic/validation-error-35/) * There is no form action for `.wp-cart-button-form`: * ```
``` * [According to specification](http://www.w3.org/TR/html5/forms.html#attr-fs-action) it must have a value so there must be at least hash (number) sign “#”. * It’s a minor problem, but it should be corrected in future versions * [https://wordpress.org/plugins/wordpress-simple-paypal-shopping-cart/](https://wordpress.org/plugins/wordpress-simple-paypal-shopping-cart/) Viewing 9 replies - 1 through 9 (of 9 total) * Plugin Contributor [mbrsolution](https://wordpress.org/support/users/mbrsolution/) * (@mbrsolution) * [10 years, 11 months ago](https://wordpress.org/support/topic/validation-error-35/#post-6231836) * Hi maxoud, thank you for reporting this.

I don’t know what I was thinking when I read this thread. My mind was somewhere else. * The plugin developers will research your issue further. * Thank you * Plugin Author [mra13](https://wordpress.org/support/users/mra13/) * (@mra13) * [10 years, 2 months ago](https://wordpress.org/support/topic/validation-error-35/#post-6232045) * Hi, You can ignore this validation warning that you are getting. HTML5 is still in an experimental stage. We can’t make changes to the plugin that may not work on some older browsers. Our main priority is to make sure the plugin works on a wider browser base. We would rather have it work everywhere than be picky about minor things (that we know for sure won’t cause any issue). * In the future when HTML5 becomes the base thats when you can validate against HTML5 and expect no warnings. * Thread Starter [maxoud](https://wordpress.org/support/users/maxoud/) * (@maxoud) * [10 years, 2 months ago](https://wordpress.org/support/topic/validation-error-35/#post-6232046) * [@mra13](https://wordpress.org/support/users/mra13/) I don’t want to generate controversy but despite of HTML5 [here is](https://www.w3.org/TR/html401/interact/forms.html#adef-action)` action` attribute definition from 16 years old W3C recommendation for HTML 4.1: * > action = **_uri_** > This attribute specifies a form processing agent. **User > agent behavior for a value other than an HTTP URI is undefined**. * Empty `action` is not a valid URI so you can’t be sure what’s the action will be assigned by UA. While HTML 4.1 covers pretty wide browser range.
