Another way would be to convert local s = Status(unit) if s then return s end local cur, max = HP(unit), MaxHP(unit) return "%s/%s || %s%%",Short(cur,true),Short(max,true),Percent(cur,max) into what it would be in Stuf, and maybe I could use that as a model to work with. Thanks in advance, -Saft

with this are you running into "nil" issues. I was having similar issues with an addon of mine. The easiest for me has been to convert. EG.
-- the sample string is 95511|TInterface\\MoneyFrame\\UI-GoldIcon:0:0:2:0|t 5|TInterface\\MoneyFrame\\UI-SilverIcon:0:0:2:0|t 12|TInterface\\MoneyFrame\\UI-CopperIcon:0:0:2:0|t

1. i had to isolate the individual demominations with match
2. next i had to remove the data i didnt want EG. |TInterface\\MoneyFrame\\UI-CopperIcon:0:0:2:0|t
   1. = = txt:match("%d+|TInterface\\MoneyFrame\\UI%-CopperIcon:0:0:2:0|t");
      1. %d+ = all occurences of all digits with matching string text.
3. i put a couple links below that helped me to understand match and sub.

-- match
  local iscopper = txt:match("%d+|TInterface\\MoneyFrame\\UI%-CopperIcon:0:0:2:0|t");
  if (iscopper == nil or iscopper == "") then
  iscopper = "0";
  end
  local issilver = txt:match("%d+|TInterface\\MoneyFrame\\UI%-SilverIcon:0:0:2:0|t");
  if (issilver == nil or issilver == "") then
  issilver = "0";
  end
  local isgold = txt:match("%d+|TInterface\\MoneyFrame\\UI%-GoldIcon:0:0:2:0|t");
  if (isgold == nil or isgold == "") then
  isgold = "0";
  end
-- replace
  local iscopper1 = iscopper:match("%d+");
  if (iscopper1 == nil or iscopper1 == "") then
  iscopper1 = "0";
  end
  local issilver1 = issilver:match("%d+");
  if (issilver1 == nil or issilver1 == "") then
  issilver1 = "0";
  end
  local isgold1 = isgold:match("%d+");
  if (isgold1 == nil or isgold1 == "") then
  isgold1 = "0";
  end
