Hello Barbara,

Thank you for reaching out to us.

Unfortunately, currently, this feature is not built-in in Amelia. You can try and hide this with this custom CSS

.am-fs__coupon > span {
    display: none
}
.el-input--prefix .el-input__inner {
    display: none
}
.am-icon-coupon {
    display: none
}
.amelia-v2-booking #amelia-container .am-button {
    display: none
}

Custom code needs to be applied to the page where the booking form is. Depending on what you're using (Gutenberg blocks, or some page builder), adding the CSS or JS can be done in a few different ways. 

If you need help with adding custom CSS to the page, please take a look at this article.

If you need help with adding custom JS to the page, please take a look at this article.

Hope this helps in case it doesn't I'll kindly ask you to add it as a feature suggestion on this link https://features.wpamelia.com/

Have a nice day. 

Hello Barbara,

Let try this CSS

.amelia-v2-booking #amelia-container .am-fs__payments-app-info-subtotal {
    display: none
}
.amelia-v2-booking #amelia-container .am-button {
    display: none
}

When we try this on our page it hides the add button and subtotal.

Hope this helps. 

Hello Barbara,

Can you please try this one

.amelia-v2-booking #amelia-container .am-button.am-button--small {
    display: none
}

You can see that when we apply it there is no button anymore

Looking forward to your reply.
