UnitName("unit") error

[Scale]

when leaving/joining raids this line sometimes gives me the error:

Usage: UnitName("unit")

local tarname = UnitName(tarframe:GetAttribute("unit"))

Now i want to create an If so it doesn't error but i don't have a clue what to check so it bypasses this line if i guess the GetAttribute("unit") is empty.

Cant you just test with:

if ( IsUnit("unit") ) then
...
end;

[Shirik]

if tarframe:GetAttribute("unit") then ...

(better yet: )
local target = tarframe:GetAttribute("unit");
local tarname;
if target then
tarname = UnitName(target);
end

You misread the question. He does not know the unit id.
