Simple javascript won't run

I am new to javascript.
Would someone please tell me why this program won't run?
I ran it on IE and FireFox, nothing other than the button showing works.
This is such a simple little program.

Thanks for any help,
Eric
I changed onclick to on click to make it throug security.

I got it figured out.
In my function I have a colon
instead of a semi-colon.

Simply turning on the Javascript console when debugging will save you a lot of hair.

will save you a lot of hair

and a lot of fur

Fur I got... it's hair that's in short supply!

Bear,
Thanks for the info on Java Console.
I didn't know such a thing existed.
My JavaScript book had some info on it which I hadn't gotten to yet.
Found out IE doesn't support it, but I have FireFox also.
I put the colon error back in and it brought it up.
Thanks,
Eric
