Changing only the Booking Form with Code

Hi Everybody,
I need a little help. I created my site using templates, only changing colors and images, etc. I love my services page, www.thebarkacademy.com/services, except for a few things. One of those things is the booking form. I have created a new booking form that I have named, BookingForm (#BookingForm). I have created a dataset called, BookingData, that I have connected the form to. now what?

I am a complete idiot when it comes to coding. I have tried to follow the “Customize your Booking Experience” tutorial, but it seems to refer to creating a new booking page. I don’t want a new page. I just want a new booking form. Is this even possible? Can anybody help?

Thanks,
Melissa
