Hehe ... this is nuts

I've looked at the code. I have started messing around on a test server like Support suggested I should. I have no clue what I'm doing. If I actually understood php, I would be writing Joomla enhancements, not buying them!

The show_product function is one thing (although I'm not at all clear as to where the code should go exactly within or next to that function, and I don't know whether or not I should replace $uid with $product or not). The lists_product function is something else. I can't find a function by that name, but I can find SEVERAL functions that include the phrase "List_Products" as part of their name. Which of these? All of them? Some of them? One of them? None of them?
Really, this is one that requires someone who understands php, and that's not me. Like I say: me customer, iJoomla creator. If JomComment can be intergrated with other iJoomla products at the backend (iJoomla News), surely it should be relatively straightforward for someone at iJoomla to explain in nice simple language where those three lines of code should go within Digistore, and what $UID should be replaced with?
This one has been mentioned a few times on the forum already, without a solution. If I use iJoomla News Portal (as I do) and can enjoy integration with JomComment there, is it really so much to expect the same for iJoomla Digistore?
And if it is so easy for a normal customer to be able to figure out - as you have suggested - then it must be a case of laziness on iJoomla's infinitely more knowledgeable and talented part that a detailed explanation isn't provided?

Your turn
