I was able to follow everything down to your last section but it seems as though I am getting off track somewhere in the process.  Where are Window height and width at in the text block settings?  
Also, is there no way to get the animated text as you have in the image overlay element?  The instructions seem to infer to use the background image in the row settings but I think you might mean image overlay?
Please watch the video in the hidden section to see where I am going wrong.  If you could clear up my confusion and clarify the instructions I would be very grateful.
