Openstudio fatal errors natural ventilation
I can't seem to find where the error is. The error is fully displayed as shown below. Where do I have to look to address this error? The zone is called "Basement thermal zone" and the object is just called "duct". I'm also not sure what out of range and blank fields I have, since I didn't change that much to the HVAC system.
Thanks in advance.

** Severe ** IP: Out of "range" values and/or blank required fields found in input
EDIT: I tried several other things but I just can't work it out. I have a simple building with just 1 room and a crawling space. Both spaces have natural ventilation and the room also has an electric heater and airconditioner (only cooling). I'm not familiair with the HVAC names, but I think I got the right heater and airconditioning. For the airconditioning I used a VRF and set the rated heat capacity to 0. Now here comes the part what seems to keep go wrong. Both the room and crawling space have natural ventilation, but they are both separate ventilation holes. The two spaces are also different thermal zones. How can I insert this? I use OpenStudio 2.3 for Windows.
I currently get this error as well:

Yes, I saw that post and I think the problem might be the second cause, but I can't find a DesignSpecificationOutdoorAir object. Where could I find that?
@Mans_sopers You will find it under Space tab just click the AirFlow button in the upper left corner. Do you have design days data? I think this is the reason for Severe Warnings.
Thanks for the answer. I did have design days, but I found that I didn't specify 'space infiltration design flow rates' and 'space infiltration effective leakage areas'. For the sake of trying to get the simulation running, I used the setttings from office CZ1-3. However, when running the simulation I now got the following error:
I can't find any mechanical ventilation however and I don't recall adding any. Where can I find this?
@Mans_sopers can you post a link to your model. i will take a look at it. The mechanical ventilation is add by the Ideal load air system.
