Gear Animation Tutorial... problems following along

I was following along with the 6 part Gear Animation tutorial (#3), and I ran into a problem right when I was supposed to call the buttons library:

local ui = require(“ui”)

Everything was working fine and dandy up until I inserted this line at the top of my code. As soon as I did that and refreshed the simulator, it went black. I take the line out and everything works fine again. I tried continuing with the tutorial and inserted the code to create the button, but as expected, that doesn’t do anything… black screen… I quadruple-checked that I wrote everything correctly.
Any input? [import]uid: 12649 topic_id: 4547 reply_id: 304547[/import]

There’s a separate ui.lua file that you have to put in your project folder. You can download that file from multiple places on this website, probably the simplest to find is the button sample app.

Also, where is this tutorial? I haven’t seen this. [import]uid: 12108 topic_id: 4547 reply_id: 14358[/import]

Thanks for the reply.

By the way, you’ll have to be more specific. I’ve only been using Corona for a few hours, so I’ll need detailed information to go on. Where exactly can I get this ui.lua file? My hard drive is littered with them and they’re all different sizes. [import]uid: 12649 topic_id: 4547 reply_id: 14429[/import]

Ooh! Nevermind, I got it. [import]uid: 12649 topic_id: 4547 reply_id: 14430[/import]
