So I'm using the trelloApi that nstrike made and yeah there's an error at .
ap = require(game.Workspace.TrelloAPI)
boardID = ap:(GetBoardID)("User Database")
ListID = ap:GetListID([All Users in our DB],[boardID])
------
game.Players.PlayerAdded(function(plr)
CardId = ap:AddCard([]..plr.Name,[]..plr.UserID,[List ID])
end)
Thanks for your help!

Take away the parenthesis, or this () away from the "GetBoardID"
@itsjoojoo Workspace.Script:3: unexpected symbol near '['
There's actually lots of syntax errors here, follow the output. Also this can help: http://wiki.roblox.com/index.php?title=Lua_errors
