Display Nested Subform values in Record Template

Display Nested Subform values in Record Template

Hi, having a really hard time with this.

In Parent form is a subform with most fields hidden, and a decision box.
Clicking the decision box invokes OpenURL to display the full subform and allow the user to create/edit each row of the subform and interact with a nested subform within the subform.

The issue I'm having, is displaying values from the nested subform in a record template.

Any ideas for displaying subforms within subforms on a record template?

Thanks!
