WoW client

WoW Classic WotLk

What happened?

Got this Lua on Wrath Classic for one of my quests in Coldarra: (no button appeared during this as well)

In addition to this Lua error, the addon doesn't seem to be working reliably in Wrath Classic. A lot of time, clicking the button will do nothing. I've also seen it highlight items but the highlight is not over the item, it's off a bit.

Lua Error Message?

2x BestSellButton\BestSellButton-2.2.2-release.lua:38: Usage: GetItemInfo(itemID|"name"|"itemlink")
[string "=[C]"]: in function `GetItemInfo'

Locals:
(*temporary) = nil

Other addons?
