could i use "PLAYER_AURAS_CHANGED" event
http://www.wowwiki.com/Events/Buff

11/8/2008 This was removed with 3.02. Use UNIT_AURA instead.

local function eventHandler(self, event, ...)
print("Hello World! Hello " .. event)
end

--
-- Create the frame
--

local f = CreateFrame("Frame", "OutsideFrame", UIParent)
f:SetMovable(true)
f:EnableMouse(true)
f:SetSize(200, 95)
f:SetPoint("CENTER", -2, 57)

--
-- Set the frame backdrop
--

f:SetBackdrop({
bgFile = [[Interface\DialogFrame\UI-DialogBox-Background]],
edgeFile = [[Interface\DialogFrame\UI-DialogBox-Border]],
tile = true,
tileSize = 32,
edgeSize = 32,
insets = { left = 11, right = 12, top = 12, bottom = 11 },
})
f:SetBackdropColor(0, 0.4, 0.8)
f:SetBackdropBorderColor(0, 0, 0)

--
-- Set the frame's drag scripts
--

f:SetScript("OnDragStart", function(self)
self:StartMoving()
end)

f:SetScript("OnDragStop", function(self)
self:StopMovingOrSizing()
end)

function functionName(args)
-- What you want it to do
end

No, put local variableName at the top of the file. You want it local to your addon, but global to the whole addon.

local critChance
function eventHandler(self, event, ...)
critChance = GetCritChance()
critChance = format("%.2f", critChance)
end

local critChance = GetCritChance()

critChance = GetCritChance()
critChance = format("%.2f", critChance)

myframe:SetScript("OnEvent", eventHandler)
myframe:Show()

myframe:SetScript("OnEvent", eventHandler(self, event)
myframe:Show()
end)

Maybe try this:

myframe:SetScript("OnEvent", eventHandler(self, event)
myframe:Show()
end)

The first option you posted is correct, this one is wrong. Functions are first-order types, you can just pass then as variables. The moment you add parenthesis, it is assumed to be a function call no longer an access to the variable. Check the lua reference manual to get a more detailed explanation on this.

local function eventHandler(self, event, ...)
local critChance = GetCritChance()
local critChance = format("%.2f", critChance)
crtm:SetText(critChance)
end
