Ha ... I surprised myself and figured out my problem. Here is the (my) solution, in case anyone else runs into the same issue.

I was not changing "ActiveDocument.ContentControls(11).Range.Text = StrDetails" to reflect the actual content item. I've changed it from 2 to 11, and it works perfectly now!

Thank you for all of your previous comments; they will help me immensely as I stumble through this project!
