Sorry for all the updates....trying to solve my own problem...while giving your Support team information to help me too. I totally created a new folder and PHP page...and tried the "Web development tutorial - Repeating Tables server behavior" tutorial. This time I was able to add the repeating table code that included [Your Repeating Content], however I was not able to drag the item binding to replace [Your Repeating Content].
The tutorial wasn't clear what I should be dragging ...it referenced dragging the ItemName binding - is this an individual column name in my binding (first name, last name...or the entire binding). I tried both..an single column name and the entire binding...but neither would replace the text. hmmmm
My table is setup as 3 columns and 5 rows.....(the Live view.....actually renders a table as such with each cell having [Your Repeating Content]...so some progress is being made.
