Well I tried to get this working but I just can't seem to no matter what I do. Would love if someone could tell me what I am doing wrong.

Here is the function I added from Cyto

function hasAccountStorage(cid, key, value)
	if isPlayer(cid) == false then
		error("[hasAccountStorage] Player not found (cid=" .. tostring(cid) .. ")")
	elseif tonumber(key) == nil then
		error("[hasAccountStorage] Invalid key (key=" .. tostring(key) .. ")")
	else
		local q = db.getResult('SELECT player_id FROM player_storage LEFT JOIN players ON player_storage.player_id=players.id WHERE players.account_id=' .. getPlayerAccountId(cid) .. ' AND `key`=' .. key .. (value and ' AND value=' .. db.escapeString(value) or '') .. ' LIMIT 1')
		if q:getID() ~= -1 then
			q:free()
			return true
		end
	end
end

And here is what I've come up with after a million and one tries.

function onAdvance(cid, skill, oldLevel, newLevel)
        if newLevel == 250 then
		if (hasAccountStorageValue(cid, 46284, 4)) then
				doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_RED, 'Congratulations on reaching 250! Unfortunately, You already have a character over this level and will not receive any points!')
		
		else
				db.executeQuery('UPDATE accounts SET premium_points=premium_points+'.. 50 ..' WHERE id=' .. getPlayerAccountId(cid))
				setAccountStorageValue(cid, 46284, 4)
				doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_ORANGE, 'Congratulations! You have advanced to level 250 and got 50 Points!')
				doBroadcastMessage('Congratulations! ' .. getCreatureName(cid) .. ' Advanced To Level 250 and got 50 Points!')
		end
	end
end

Thanks in advanced for anyone that can assist me!
