Thanks Phanx. Now i have one more small(ish) problem.

I changed my TOC to:

## Interface: 40300
## Title: Tribal XP Bar
## Notes: Tribally XP Bar of Prettiness
## Author: Othgar
## Version: 1.0b
## SavedVariablesPerCharacter: TXPVisible, TXPLocked, TXPTexture

TXP.lua

and changed the Lua file to:

-- Tribal Experience Bar
-- By: Othgar
-- Copyleft All Rights Reversed

-- Default state
TXPVisible = true;
TXPLocked = true;

-- Constants
local ThousandSeparator = ","

        local left, num, right = string.match(n .. "", '^([^%d]*%d)(%d*)(.-)')
        return left..(num:reverse():gsub('(%d%d%d)', '%1'.. ","):reverse())..right
end

local TribalExperienceBar = CreateFrame("StatusBar","TribalExperienceBar",UIParent)

--Tooltip

local function OnEnter(self)  
	GameTooltip:Show()
end

local function OnLeave(self)  
	GameTooltip:Hide()
end

--hide @ 85
if UnitLevel("player") >= 85 then
	TribalExperienceBar:Hide() print("Experience bar hidden, type /TXP show to show.")
	TXPVisible = false
end

and it's saving the texture as a variable I think because I set the texture simple (for example) and do /rl, and I get "Texture already set simple." printed in the chat window. However the texture isn't showing up until I set it again with the slash command, and after another /rl I have to set it again.

Edit: After some more testing it seems that the texture remains set and appears after changing zones, but a /rl or logout requires me to reset the texture via slash command.
