how to add 'impact' and 'servcie_offering' when VA is creating incident with scripts

[SonnyY]

The following script is to create incident with 'short_description', 'Urgency' etc. The Virtual Agent is using this code to create incident.
I want to also add 'Impact' and 'Service_offering'. However, it did not work when I did the following:

-duplicate this script and create a new one;
-add 'impact' and 'service_offering' in line 6
-add new lines to set value of 'impact' and 'service_offering' between line 15 and line 16.

Please shed some light on how to achieve this.
