Hi Russ,
We have existing methods to traverse through the Task response data, or collection variables.
1. Loop for each action is used to process collections of data - This will allow you to extract the values from each response. https://help.nintex.com/en-US/nwc/Content/Designer/Actions/LoopforEach.htm ( https://help.nintex.com/en-US/nwc/Content/Designer/Actions/LoopforEach.htm )
2. The next step depends on how you want to consume this data. One option is to use Create a text string and use the values from Loop for each. https://help.nintex.com/en-US/nwc/Content/Designer/Actions/CreateaTextString.htm. ( https://help.nintex.com/en-US/nwc/Content/Designer/Actions/CreateaTextString.htm )
I have attached screenshots of an example of a workflow design that will extract the Responder and their corresponding Comment. The next image is of how the text string will print.
If you have any further questions around this scenario, or anything else in NWC, please reach out to me directly - kate.huynh@nintex.com ( https://mailto:kate.huynh@nintex.com )
