Based on everything I've read about this mod, I still can't figure out how it works. Does it display products from a certain category automatically? Or do you have to manually set which products display?
Right now using "Ultimate Cross Sell for Zen Cart" and it is very annoying because every product has to be set individually. This is not good because there is a lot to manage, and if a product is sold out then it still displays unless you manually remove it.
