AirLoopHVAC:SupplyPath / AirLoopHVAC:ReturnPath Input

edit

I was trying to modify an existing IDF file to include a certain zones within the file. I am keep getting the below error for a certain air loops. All the details are the same for these air loops and others. Could anybody give me a hint on how to fix this problem.
