What this script is for is basically a bottles system like in the 3D zeldas. In this version, you must have a total of XY items where x is the number of bottles in the quest and y is the number of possible items that a bottle is required for. Then whenever you "talk" to an FFC with this script on it, it's a shop script basically. it checks link's inventory for bottle items (of unique item classes, in my case zz251-254) and either gives him the appropriate potion item, or tells him to stop being a punk-ass cheapskate, or tells him that he needs a bottle of potion-holding. 
A bug with Arrays? [RC5]
