Say Health

[NeXxUSA]

Hello, I need some help. This code doesn't work. As far as what it's supposed to do that is documented function by function below, as well as a general overview in the final comment. Please help me fix this. This is my first addon I'm going to see through to the end, as I scrapped my last one due to it being too advanced.

	
	
--Check if right alt key is down. If true returns 1.
local function altDown()
    local isDown = IsRightAltKeyDown()
    return isDown
end
--Get current health
local function getHealth()
    local cHealth = UnitHealth("player")
    return cHealth
end
--Get max health
local function getMHealth()
    local mHealth = UnitMaxHealth("player")
    return mHealth
end
--All functions have bee declared
 
--If the function altDown returns 1, say current health over max health. Else, end. 
if altDown() == 1
            then SendChatMessage(getHealth() .. "/" .. getMHealth())
            else
end
--Purpose of the addon is to say "health/max" in /say chat when you press right alt.

Thanks!
