hi,

i installed CowTip_LuaTexts today and tried to write my old DogTag lines @ LUA

but i have an issue, everytime i get an error like this

-> bad argument #1 to 'format' (string expected, got no value)

here are my lua lines

line 1:

local name = Name(unit)
if not name then
 return "UNKNOWN"
else
 name = Colorize(("%s"):format(name), ClassColor(unit))
 return name
end

line 2:

local level, race = Level(unit), SmartRace(unit)
local class = ""
if UnitIsPlayer(unit) then
  class = Colorize(Class(unit), ClassColor(unit))
else
  class = ""
end
level = Colorize(level, DifficultyColor(unit))
local diff = ShortClassification(unit)
return "Level %s%s %s %s", level, diff, race, class

line 3:

local guild, _, _ = GetGuildInfo(unit)
local pguild, _, _ = GetGuildInfo("player")
if not guild then
 return
else
 if pguild == guild then
  guild = Colorize(("[%s]"):format(guild), 0, 255, 255)
 else
  guild = Colorize(("[%s]"):format(guild), 250, 182, 0)
 end
 return "%s", guild
end

line 4:

if TalentSpecName(unit) and TalentSpec(unit) then
  return "%s %s", TalentSpecName(unit), TalentSpec(unit)
else
  return
end

line 5:

local name = Name(unit .. "target")
if not name then
  return
else
  if name == UnitName("player") then
    name = "You"
  end
  name = Colorize(name, SmartClassColor(unit .. "target"))
  return "Target: %s", name
end

maybe u find my failure (i'm not that good in lua ^^)
