HELP! Can'r run a basic applet in JBUILDER 8

[Steve Jensen]

I'm using JBuilder 8 (enterprise edition)
I REALLY need some help folks.
I think this is an IDE problem, but i'm not sure. And cosidering the Applet chapter in the book i'm following (Sams Java in 21 days) comes before the chapter on packages, i think his could well be an IDE issue.
OK, here goes...........
My problem involves following the Borlan tutorial on applets, found at:-
JBuilder Applet Tutorial

I'm trying to run an applet, so i've followed the tutorial that accompanies JBuilder 8, the GoodEviningApplet, in particular, the web page.........

step2, point 10

Now, i've got to step 2, point 10.
But here, at point 10, I get an error!
When i click on my GoodEveningApplet.java file, to open it up, I see an error.
The error says:-
"Class Applet not found in class firstapplet.GoodEveningApplet at line 16"
What is going on??

All i did was follow the instructions from the tutorial!!
ANY help would be GREATLY appreciated, as i haven't a clue what i'm doing wrong!!!
Cheers in advance!
