Issue adding a new shipping carrier.

Hello, I’m trying to add a new carrier called “Seur”. This company works in Europe and my country Spain but I don’t know what to do to get the tracking URL properly to make it working with the tracking number.
This is the URL for tracking orders: http://www.seur.com/livetracking/pages/seguimiento-online-busqueda.do
I added a tracking code as example privately.
