Hi guys.
So I need some help with multisell, I started creating a server, just for fun, and I made some custom files (like armor, weapons, accessories... all default in game items, just changed the stats a bit), made a custom gm shop, with multisell files and all, but I wondered how other server developers make that when you buy (let's say 1 lvl Bow) and when you decide to buy a second level weapon, the multisell shows the player ONLY the 2 lvl Bow and NOT the other 2lv weapons like (dagger's, dual's, sword's, blunt's and all other weapons...) But if the player doesn't even have the 1st level weapon, the multisell would show an empty list with no items in the shop. So basically what I've been searching for is probably called an Upgrade Shop or smth, but still, could't find any info about that anywhere..
Can maybe anyone share with me a multisell file or the code it self, so that I would know how it's done ? (excuse my bad English skills, i tried my best, hope you understand what I meant to say)
EDIT:
BTW I'm using L2jFrozen, Interlude..
