Collect Employee Input - update HR Case

Hi folks,

Having some issues with using the Collect Employee Input HR task on one of our HR Services. I am following the instructions from the docs site here. The form has been designed with the questions I need to get a response to (in this example the subject person's manager).

The task is sent out successfully (triggered as a service activity) to the subject person's manager. When they complete the form via the To-Do's section, their response is not updated into the HR Case.

I am trying to figure out how to get the responses into the additional comments or work notes of the parent case. Or do I have to create fields on the HR case table to map the responses to?

Thanks for your assistance!
