Need help with this scripting.

No, it's the name of the variable. You can use any name you want, you can even stay by that. It doesn't matter.

sorry but what goes in the
stuff you want to happen always comes here? Is it the AddEntityCollideCallback?

I don't know your script, neither what you want to achieve, but what I've read so far is that you want a grunt to always appear, and a fadeout only once? If so, add the FadeOut to the area for "stuff that only works once" and the grunt part to the other.
