Aloha, I'm back with an example. My situation seems different than solutions in recent threads, and I don't see how the answers thus far apply (if they do). I'm looping through the results of a catalog search, displaying thumbnail images, caption, date, etc.. A thumbnail, linked to a full-sized image, is displayed for each result: ... <a href="<dtml-var imageURL>"> <img src="<dtml-var thumbURL>" border="0" alt="<dtml-var caption>"> </a> ... imageURL and thumbURL are properties of each gallery item which point to the actual image, and will be something like: /gallery/thumbs/C03Valley001.jpg I want to get the height and width attributes from each thumbURL item and use them in the img tag attributes. But: height="<dtml-var thumbURL.height>" does not work, giving: Error Value: exceptions.KeyError on thumbURL.height in "" I am assuming this is because in my situation all thumbURL items returned are objects with periods in their IDs. So it's choking on trying to find '/gallery/thumbs/C03Valley001.jpg.height' - is this the case? Or is there some other problem here? In any case, how do I access the attributes (like height and width) in this situation, where the period in the actual ID is 'implicit' in thumbURL? thx, John S. __________________________________________________ Do You Yahoo!?
