Folks, Thanks for the 'help'. Oy. I figured it out from some help on the Lasso discussion list.
All I had to do was properly address ALL the tables I wanted to touch. So this: UPDATE tbe_gallery SET tbe_gsa.gsa_paperprice = tbe_gallery.gallery_gsaprice_paper WHERE tbe_gallery.gallery_id = tbe_images.img_rel_id AND tbe_images.img_orig_filename = tbe_gsa.gsa_id Should have been This: UPDATE tbe_gallery, tbe_gsa, tbe_images SET tbe_gsa.gsa_paperprice = tbe_gallery.gallery_gsaprice_paper WHERE tbe_gallery.gallery_id = tbe_images.img_rel_id AND tbe_images.img_orig_filename = tbe_gsa.gsa_id And viola, it works! Miles.
