revski, im looking at my code deeper now. i upgraded and didn't do a clean install. my old versions do indeed have a modules/your_template folder...i see now early in the readme where it mentions that, but for my install, i skipped to the upgrade parts...missed that. there is no folder/file to edit or overwrite in the last downloadable version of this mod. I do have the template folder in my live store site files. it's attributes.php AND that is most likely why my quantity updates work when i use the old way, one at a time update. the ajax doesn't work for me, is this the reason???, the includes/modules/YOUR_TEMPLATE /attributes.php file is not changed....i can't help you any more that this. there seems to be a folder missing in the last updated download.
