OK, have at it! I'll be confirming my "novice" status by revealing this code, but at least you won't be able to see me blush.
I am first listing info on a database of photos by theme, then allowing the user to pick the specific photographer he/she wants to see. This is the tough page for me: http://redwood.jmdl.com/themes.cfm http://redwood.jmdl.com/themes_code.cfm (code) The combination of a loop over the initial query and the delimited field (example, Henry Gilpin's same photo appears under "Iconic" and "Landscape") are what is kicking my butt. It works the way I have it now, but it's ugly, ugly, ugly and certainly wastes unnecessary resources. Thanks to anyone who can school me.
