CZML Vehicle

I have been looking at the CZML sandcastle example and would like to replicate the vehicle tracks in my application. I have attempted to do so but with no success. My first question is that do you need to use the built-in CZML as well as czmlVehicle(); or can that be used on it's own? I have tried both ways anyway.

I think I am using the right code from the example but nothing seems to be working so if anyone could help point me in the right direction I would much appreciate that thanks!

Adam, are you simply trying to load an external file? Or do you want to programatically read in/modify/or generate data and populate objects?

Not to worry I managed to get it working!

I was having problems because I was using the Cesium widget and once I changed to viewer this solved my issue.
