New to creating oUF needs help

[ahhnam]

I am pretty new to programming so for the past week I was looking into other people's oUF files to try to get a basic understanding of what to do and come up with something that doesn't seem to work properly and I can't really figure out why and was just wondering if anyone can give me some pointers. Thank you.

-- Framework

local function Func(self, unit)
	self.colors = colors
	self.menu = menu
	
	self:RegisterForClicks('anyup')
	self:SetAttribute('*type2', 'menu')
	
	self:SetScript('OnEnter', UnitFrame_OnEnter)
	self:SetScript('OnLeave', UnitFrame_OnLeave)
	
	self:SetBackdrop(backdrop)
	self:SetBackdropColor(0, 0, 0)

-- Health Frame
	
	self.Health = CreateFrame('StatusBar', nil, self)
	self.Health:SetHeight(20)
	self.Health:SetWidth(200)
	self.Health:SetPoint("TOPLEFT")
	self.Health:SetPoint("TOPRIGHT")
	self.Health:SetStatusBarTexture(minimalist)
	self.Health.frequentUpdates = true
	self.Health.colorSmooth = true
	self.Health.colorClass = true
	
	self.Health.bg = self.Health:CreateTexture(nil, 'BORDER')
	self.Health.bg:SetAllPoints(self.Health)
	self.Health.bg:SetTexture(0.3, 0.3, 0.3)
--

-- Power Frame

	self.Power = CreateFrame('StatusBar', nil, self)
	self.Power:SetHeight(3)
	self.Power:SetWidth(200)
	self.Power:SetPoint("TOPLEFT", self.Health, "BOTTOMLEFT", 0, -3)
	self.Power:SetPoint("TOPRIGHT", self.Health, "BOTTOMRIGHT", 0, -3)
	self.Power.colorSmooth = true
	self.Power.frequentUpdates = true
	self.Power.colorPower = true
--

end

oUF:RegisterStyle('3xp', Func)
oUF:SetActiveStyle('3xp')

oUF:Spawn('player'):SetPoint('CENTER', UIParent, -220, -250)

Yep that's it, I tried to see if I can get the basic working before going further and so far it's still failing.
