How to get Q_PopulateResponse to work for side-by-side and matrix tables

I am having difficulty getting Q_PopulateResponse to work for me. I uploaded the prior quarter's answers as Embedded Data to the contact list, and tried setting up the link in my distribution email. However, nothing was populated. This the string I used:
