Position of 'Register' button on WooCommerce registration page is wrong.

Hi,

I am trying to change the position of the customer registration button on the WooCommerce login/my account page. Exactly like in this thread:
https://kriesi.at/support/topic/woocommerce-registration-login-page-layout/

but I have tried entering this:

#customer_login input[type=”submit”] {
float: none !important;
}

into the custom css.

but it doesn’t work for me this code. Please could you help me try to do this? The position of the ‘register’ button is basically half in/half out the registration box and I would like it to be inside the box like the ‘login’ button in the left column.

Thanks!
Jamie
