ads.init( admob, 286480765967, adListener )
The second parameter should be a string and is typically your banner app id for the platform you’re on.

Hi,
So I managed to run the ads in the balloon tap. Thanks. However trying to apply similar to my app isn’t working. No matter where I call the ad, it creates an error:
09:14:31.317 E:\Projects\Apps Games\Corona Projects\Blow Stuff Up\gameScene.lua:14: attempt to index global ‘ads’ (a nil value)
09:14:31.317 stack traceback:

Here’s my gameScene.lua code where I’m trying to call the banner ad:
local composer = require( “composer” )
local scene = composer.newScene()
local ragdogLib = require “ragdogLib”;
local networksLib = require “networksLib”;
–local adsLib = require “adsLib”;
– All code outside of the listener functions will only be executed ONCE unless “composer.removeScene()” is called.
– local forward references should go here

Try changing
local ads = require( "ads" )
to
ads = require( "ads" )
in main.lua.
You need to require ads in your scene. Near the top do:
local ads = require( “ads” )
@bgmadclown’s suggestion will also work, but it’s creating a global variable. In this case creating a global for ads isn’t a bad thing, but if you don’t have a firm grasp on scope, you will start leaning on globals to work around scope and that will lead to problems, so avoiding them is a healthy habit and the cost of a little more typing.

It works!! Thanks!
The other thing I’m trying to get working is the leaderboard. It’s supposed to automatically sign me in but it doesn’t. Hence when I click on the leaderboard button, nothing happens.
What can I do?
You are trying to make us do all the work for you. Sorry, I’m out.
Hey @admin2949, this thread is about AdMob. Asking about Leaderboards is called “hijacking the thread” and leads to confusion among people looking for solutions. When you need to change subjects please start a new thread or search for a similar thread for your question. It’s like been previously answered.
