I am presenting data from a .csv file as a repeating table on one of my 
pages.  I am able to create a popup window 'on-the-fly' to display some of 
the data if I explicitly pass the data as parameters, but I can't see how 
to pass the field contents when a user clicks on a cell.  Each row 
represents one record in the usual way, and one cell contains the link, in 
this case an image URL.  How do I get the contents of that record into the 
popup window function, so the image and other field data display?
