I suck at this (first proper mod help)

[Sjak]

Ok, I've spent the last day or so trying to make this work. I'm making a mod that will display some text when a buff is missing from the player (specifically an aura/blessing). However, using the "UIErrorsFrame" doesn't work because my message doesn't stay there - it fades and then doesn't come back. How would I make a message stay on the screen until the buff is found?

This is the main function for buff finding:

function CheckForAura(auraName, unit)
	auraName = auraName or "" 
	unit = unit or "player" 
	local i = 1
	local n = UnitBuff(unit, i) 
		while n do 
			if strfind(n, auraName) then 
			return true 
		end
	i = i + 1
	n = UnitBuff(auraName, i) 
	end
end

Thanks
