What happens when two Court orders seem to conflict?

In my case, there is an order from 2010 requiring me to have supervised visitation. That order is still in effect. That order requires me to be 100% responsible for the costs of supervised visitation. In 2013 an Order for Child support was entered. That order states that I am only 24% responsible for costs related to travel for parenting time over 100 miles. My ex now lives over 100 miles away. Supervisors cost more in my ex's new location to where I now travel. Am I now only responsible for 24% of the costs of supervised parenting time because of the increase as a result of traveling, or 100% of the costs? Which order applies? The newer or older, or do both still apply? Thanks!
