weak aura halp

[bargiddle]

so im trying to get a weak aura to work better then it does atm. i have one that shows my targets name and percent while in combat, but if i happen to lose target, or for some reason am forced to target nothing for any amount of time, it spams me with errors

is the offending aura, and the part doing all the work is

function()
    local percent = (UnitHealth("target")/UnitHealthMax("target")) * 100;
    return ("%s - %i%%%%"):format(UnitName("target") , percent  or 0);
end

it works perfectly while in combat and i have a target, just trying to prevent the error spam upon losing a target

This should work:

function()
	if not UnitExists("target") then return "" end;
	local percent = (UnitHealth("target")/UnitHealthMax("target")) * 100;
	return ("%s - %i%%%%"):format(UnitName("target") , percent  or 0);
end
