If you want to present more than one block, just add extra Loop and Merge Lists. Use standard Qualtrics question blocks to present information in between these blocks (and unhide them using the code explained here http://www.qrtengine.com/tutorials/stroop-task-web-adaptation/, search for “unhide”). Make sure you make the blockIDs and all object names/ids/tags etc. unique, otherwise the data might not be stored and/or parsed correctly. The sequence of blocks can be modified easily (drag and drop) in the Survey Flow view.
Hope that helps!
