Create a Search for Booking Services

Hello - I am new to Corvid, not good with code at all, but trying my best… I am trying to create a website that will have over 100 services on it, I’d like it tied to the Bookings calendar and Staff that can fulfill the service. I found there’s no way to setup a clean filter for Services like there is for Products, so I thought a search function into a user input would work better and from there applicable services come up as the customer types them in. In trying to tie it to the Bookings database collection where I have all of the services listed out, when I do so I get this error message “The collection connected to this dataset has been removed. Delete the element or connect the element to a different dataset”. Does anyone know what this means, or what I need to do to have a searchable input for all of my booking services? Any sample code is appreciated as well. Thank you in advance!
