Hello Angélique,

Thank you for reaching out to us.

On which booking form would you like to hide it specifically?

Looking forward to your reply.

Hello Angélique,

Thank you for clearing that up.

Please try the following CSS and let me know if it works or not:

.am-service-dropdown .am-select-service-price{
    display: none !important;
}
.amelia-v2-booking #amelia-container .am-fs__payments .am-amount {
    display: none !important;
}
.amelia-v2-booking #amelia-container .am-fs__payments-services-sub p {
    display: none !important;
}
.amelia-v2-booking #amelia-container .am-fs__congrats-info-customer > div:nth-child(5) {
    display: none !important;
}

Looking forward to your reply.
