Help with Loading and Using Saved Variables

[cokedrivers]

So im trying to load and use the saved varables for my addon.
Here is the current lua code:

local addon, sActionbars = ...

SlashCmdList['RELOADUI'] = function()
	ReloadUI()
end
SLASH_RELOADUI1 = '/rl'

function sActionbars:RegisterDefaultSetting(key, value)
    if ( sActionbarsDB == nil ) then
        sActionbarsDB = {}
    end
    if ( sActionbarsDB[key] == nil ) then
        sActionbarsDB[key] = value
    end
end

function sActionbars:SetDefaultOptions()
    sActionbars:RegisterDefaultSetting("showHotKeys", false)
    sActionbars:RegisterDefaultSetting("showMacronames", false)	
end

function sActionbars_OnLoad(self)
    self:RegisterEvent("ADDON_LOADED")
end

function sActionbars_OnEvent(self, event, ...)
    if ( event == "ADDON_LOADED" ) then
        local name = ...
        if ( name == "sActionbars" ) then
            sActionbars:SetDefaultOptions()
            self:UnregisterEvent("ADDON_LOADED")
        end
    end
end
	
local hotkeyAlpha = sActionbarsDB.showHotKeys and 1 or 0
local macroAlpha = sActionbarsDB.showMacronames and 1 or 0

for i = 1, 12 do
	_G["ActionButton"..i.."HotKey"]:SetAlpha(hotkeyAlpha) -- main bar
	_G["MultiBarBottomRightButton"..i.."HotKey"]:SetAlpha(hotkeyAlpha) -- bottom right bar
	_G["MultiBarBottomLeftButton"..i.."HotKey"]:SetAlpha(hotkeyAlpha) -- bottom left bar
	_G["MultiBarRightButton"..i.."HotKey"]:SetAlpha(hotkeyAlpha) -- right bar
	_G["MultiBarLeftButton"..i.."HotKey"]:SetAlpha(hotkeyAlpha) -- left bar
end

for i = 1, 12 do
	_G["ActionButton"..i.."Name"]:SetAlpha(macroAlpha) -- main bar
	_G["MultiBarBottomRightButton"..i.."Name"]:SetAlpha(macroAlpha) -- bottom right bar
	_G["MultiBarBottomLeftButton"..i.."Name"]:SetAlpha(macroAlpha) -- bottom left bar
	_G["MultiBarRightButton"..i.."Name"]:SetAlpha(macroAlpha) -- right bar
	_G["MultiBarLeftButton"..i.."Name"]:SetAlpha(macroAlpha) -- left bar
end

local function UpdateRange( self, elapsed )
	local rangeTimer = self.rangeTimer
	local icon = self.icon;

	if( rangeTimer == TOOLTIP_UPDATE_TIME ) then
		local inRange = IsActionInRange( self.action );
		if( inRange == false ) then
			-- Red Out Button
			icon:SetVertexColor( 1, 0, 0 );
		else
			local canUse, amountMana = IsUsableAction( self.action );
			if( canUse ) then
				icon:SetVertexColor( 1.0, 1.0, 1.0 );
			elseif( amountMana ) then
				icon:SetVertexColor( 0.5, 0.5, 1.0 );
			else
				icon:SetVertexColor( 0.4, 0.4, 0.4 );
			end
		end
	end
end

do
	hooksecurefunc( "ActionButton_OnUpdate", UpdateRange );
end

Here is the xml file that loads before the lua file:

<Ui xmlns="http:\\www.blizzard.com\wow\ui\" xmlns:xsi="http:\\www.w3.org\2001\XMLSchema-instance" xsi:schemaLocation="http:\\www.blizzard.com\wow\ui\ ..\FrameXML\UI.xsd">

	<Script file="sActionbars.lua"/>
	
    <Frame name="sActionbars">
        <Scripts>
            <OnLoad function="sActionbars_OnLoad" />
            <OnEvent function="sActionbars_OnEvent" />
        </Scripts>
    </Frame>
	
</Ui>

But when i log into WoW it thows me this error:

1x sActionbars\sActionbars-8.1.0.lua:36: attempt to index global 'sActionbarsDB' (a nil value)
sActionbars\sActionbars-8.1.0.lua:36: in main chunk

Locals:
addon = "sActionbars"
sActionbars = <table> {
 SetDefaultOptions = <function> defined @sActionbars\sActionbars.lua:17
 RegisterDefaultSetting = <function> defined @sActionbars\sActionbars.lua:8
}
(*temporary) = nil
(*temporary) = <function> defined @sActionbars\sActionbars.lua:3
(*temporary) = nil
(*temporary) = nil
(*temporary) = nil
(*temporary) = nil
(*temporary) = nil
(*temporary) = nil
(*temporary) = nil
(*temporary) = nil
(*temporary) = "attempt to index global 'sActionbarsDB' (a nil value)"

What am I doing wrong here?

Thanks
