I followed the Data Assist Wizard as you suggested and I got the Search, Results, and Details pages working fine. I've been able to tweak the different features to make the whole thing look very close to the way I want it and the Results page is linking perfectly well to the Details page when clicking on the Thumb images.
However, there's still one thing that maybe you can help me with:
Is there a way to target the Details page so that it opens on a particular "content div" in the Results page? As it is, the Details page opens on a new page in the Browser. How can I make DW/WA open it (target it) in an existing div in the Results page?
Thank you for your attention.
