defining system type

1 post / 0 new

I recently changed the thermostat schedule and design air flow (to 1 cfm/ft?) for a bunch of zones on a VAV air handler. After saving this change and reloading the project, I get an error "TYPE NOT FIRST KEYWORD" for each zone I changed.

I'd understand this if each zone had its own system, but all these zones are assigned to the same VAV AHU. The system TYPE is defined at the top of the system definition as VAVS. A portion of the .inp file showing the system definition and the first error-causing zone is included below.

Any idea what might be causing this error? Any help is appreciated.
