Troubles with joining info out of to data sets into one

Question:
Hi Guys trying to make a bookingsystem that consists out of 2 parts. 1. The client info 2. The airporttransfer info + price.

Dataset 1 : Transfers is starting point selection + end point selection and that is returning a price
Dataset 2 : General infoclient
Now I want to add the info dataset 1 into data set 2 to have a complete overview of the booking and try to find a way tot confirm it to the customer + online payment.
