Team,

This is the first time I am using Document Designer as we are using HTML Attributes to Display and download the summaries. I am trying to get the Configuration Array information in the document designer however I am failed to get the values. I have followed the steps mentioned in the CPQ help page, still no values appear.

I have selected text element and Applied loop. Inside the loop, I am able to select the configuration array set and save. After saving and deployed, I am not able to see the values of the Array which I have configured in the quote. No doubt on assigning doc to Print action.
