Questions about Global Variables

I'm creating a game that has a "Life" Global Variable that I want persistent throughout all of the layouts.

First of all, I want to display the value of "Life" in a text box, but I'm having trouble doing so. So far I have

"Lives: " &[/code:m4haskfd]
How would I add the value of "Life" to that? 

And also, I want an event for when "Life" goes below 1, but I don't know how to do that either. Can anyone help with this?

Have you tried the Ghost Shooter tutorial? It covers some of this.

For lives you want:

"Lives: " & global('Life')

There's also a condition in the system object to compare a global variable.

Thank you! I knew it was going to be something really simple, but I just couldn't find it anywhere in the documentation or on here.
