First wow mod, need help to trouble shoot.

[Calabera]

First of all, thanks for taking the time to visit my post.

I have some programming background, I used to study CIS before I decided to join the military and go in a medical career.

Now, I am trying to make a simple mod using nothing but local values.

I want the mod to detect if I have Dark Intent up, if I have Improved Soul Fire up, and last but not least to see if Conflag is off from CD. (Yes I play a warlock)

EventFrame:RegisterEvent("PLAYER_LOGIN")


function CalaberaAnnounce:PLAYER_ENTERS_COMBAT()

local myDarkIntent
       myDarkIntent = UnitBuff("player", "Dark Intent");
end;
else
  DEFAULT_CHAT_FRAME:AddMessage("You are missing Dark Intent!");
end;



--- Improved Soul Fire Check

local impSoulFire
       impSoulFire = UnitBuff("player", "Improved Soul Fire", 2)
end;
else
  DEFAULT_CHAT_FRAME:AddMessage("You are missing Improved Soul Fire!")
end;

--- Conflag Check

lolcal conflagCDC
 local start, duration, enabled = GetSpellCooldown("Conflagrate");
if enabled == 0 then
 DEFAULT_CHAT_FRAME:AddMessage("Conflag is ready for use!");
elseif ( start > 0 and duration > 0) then
 DEFAULT_CHAT_FRAME:AddMessage("Conflag is on Cooldown " .. (start + duration - GetTime()) .. " secs to be up.");
else
DEFAULT_CHAT_FRAME:AddMessage("Conflag is ready for use!");
end;

Where did I go wrong with this in my Lua?
