hp text disappear on max health

[Toran]

Hi -

I'm modifying Freeb's awesome oUF layout to my liking and would like to hide the *player only* hp text information on max hp (and have it appear when hp is lost). This is the chunk I was going for in Freeb's ftags.lua:

oUF.Tags['freeb:hp']  = function(u) 
	local min, max = UnitHealth(u), UnitHealthMax(u)

	if(unit == "player") then
		if(min < max) then
			return siValue(min).."."..math.floor(min/max*100+.5).."%"
		else
			return bar.value:SetText(" ")
		end
	else
	
        return siValue(min).."."..math.floor(min/max*100+.5).."%"		
	
        end

end

No errors, but it doesn't hide the hp info on max health. Any ideas? Thanks.
