Using a value in a frame name

[Ereki]

I have looked through it but I can't say it helped that much but I now I pretty much took their code and used it for my purpose so this is what I have now:

elseif event == "RUNE_POWER_UPDATE" and InCombatLockdown() and not UnitInVehicleControlSeat("player") then
	local runeIndex, isEnergize = ...;
	local runeButton = _G["RuneButtonIndividual"..runeIndex];
	local start, duration, runeReady = GetRuneCooldown(runeIndex);
			
	if not runeReady and not isEnergized then
		if start then
			runeButton:SetAlpha(RHaoc)
		end
	else
		runeButton:SetAlpha(RHaic)
	end

	if isEnergize then
		runeButton:SetAlpha(RHaic)
	end

and this is the blizzard code:

local runeIndex, isEnergize = ...;
if runeIndex and runeIndex >= 1 and runeIndex <= MAX_RUNES  then 
	local runeButton = _G["RuneButtonIndividual"..runeIndex];
	local cooldown = _G[runeButton:GetName().."Cooldown"];
	
	local start, duration, runeReady = GetRuneCooldown(runeIndex);
	
	if not runeReady  then
		if start then
			CooldownFrame_SetTimer(cooldown, start, duration, 1);
		end
		runeButton.energize:Stop();
	else
		cooldown:Hide();
		runeButton.shine:SetVertexColor(1, 1, 1);
		RuneButton_ShineFadeIn(runeButton.shine)
	end
		
	if isEnergize  then
		runeButton.energize:Play();
	end
else 
	assert(false, "Bad rune index")
end

And I'm still getting the same results as before...
