Weather for trip to upcoming city

Ok, since it is impossible to find this with a Google search.

I am using Tripsy and Carrot weather on my iPad (OS 16). All I would like to happen is Shortcuts gets the city for my next trip from Tripsy and feeds that into Carrot Weather and it gives me a forecast.

In the Shortcuts app I have a Carrot action for Get Current Conditions for” and then it has the Trips icon with the word “City” in red. I guess this is a variable? How do I extract the City for my upcoming trip from Trips to fill this variable?
