phpbb forum mod hack

I am currently running a fresh install with a few mods of phpbb 2.0.19. The forums work great, and all of the mods are done correctly. One of the mods is a store mod (WGeric Store Mod [[login to view URL];postdays=0&postorder=asc&start=0]). The forums will be for an online miniature based game, and what I need is for the store to have 'booster packs' (like packs of random pieces). The store mod has an effects package, that lets you use items that you buy from the store, and it runs a code which is designed for that item. I have edited this code, and have it working...somewhat. What I need is for somebody to clean up the code, and essentially get it working coreectly, as it does not work totally right yet, and I am stuck with no clue what to do. Basically it is supposed to give the person who uses the item, 11 random items from the store. Then it checks to see if the person has any of the items, if so, updates to the new amount, or if they don't have the item, adds it to their inventory. As it sets, it does not update the amount owned, it only returns 1 or 2 items (instead of 11), and it is always the same item. It also does not display the items taken from the 'booster pack', just the empty windo where it should state it. You will need to likely have knowledge of the phpBB setup, and probably the store mod too, just as a referance. That probably depends on how comfortable you are with the forums, mods, or maybe even taking a look through to see what is going on. It is only one file which will need fixing / editing, and does not rely on any other pages for the most part. Like I said, most all of the code is there, I just can't get it working all correctly. If your interested in this, let me know any questions you might have. Thanks for your time.
