Concentration Game Tutorial Crashing - Source Available

Hello everyone! I’m a newbie.

I am attempting to run the code from this tutorial.

http://code.tutsplus.com/tutorials/corona-sdk-build-a-concentration-puzzle-game–mobile-20353

When I launch main.lua with corona app simulator I get the following errors.

File: main.lua line:78 ERROR: table expected. If this is a function call, you might have used '.' instead of ':' stack traceback: [C]: in function 'newGroup' main.lua:78: in function 'Main' main.lua:197: in main chunk

Line 78 is this:

titleView = display.newGroup(title, playBtn, creditsBtn)

and it’s part of this function:

function Main() title = display.newImage('title.png') playBtn = display.newImage('playBtn.png', 130, 248) creditsBtn = display.newImage('creditsBtn.png', 125, 316) titleView = display.newGroup(title, playBtn, creditsBtn) startButtonListeners('add') end

You can download the code from this tutorial, which looks pretty useful, from the download link on the site here.

Then you should be able to run it and, hopefully, crash like I crash!

Thanks for any help! I think I can learn a lot from this one if I can get it to run smoothly.
