Number of participant in WixBooking Form

#WixBooking #formfields #collection

Hello,
As many people on the forum, i have tried to follow the tutorial to have a timetable related to wix booking ( https://support.wix.com/en/article/corvid-creating-a-bookings-timetable ; https://support.wix.com/en/article/corvid-creating-a-bookings-timetable#overview )
Everything is working well until the end of the booking process.
But in the form of the lightbox, there is a field missing (“number of participant”)
Could you please tell me why this field is missing and how i can manage to display this field?

Is it a problem related to my wix booking service collection?
In the classical Wixbookingform the field "number of participant exists.

The page : https://www.upakramayoga.com/blank
The code of the lightbox that rule the field:
//-------------Lightbox Setup-------------// $w.onReady( function () { // Get the data sent from the Schedule page. const context = wixWindow.lightbox.getContext(); // Set the global slot to the slot that was sent from the Schedule page. slot = context.slot; // Get the form fields that were sent from the Schedule page. const fields = context.form.fields; // Set the form repeater’s data to the form fields. $w(" #formRepeater “).data = fields; }); //-------------Repeater Setup-------------// // Set up each item in the form repeater as it is loaded. export function formRepeater_itemReady($item, itemData, index) { // Set up the item’s input field. $item(” #input “).placeholder = itemData.label; $item(” #input “).inputType = itemData.type; $item(” #input “).required = itemData.constraints.required; $item(” #input ").resetValidityIndication();
Thank you for your time and help.
