Snowflakes Script Help!

Script: Snow Effect All


http://www.dynamicdrive.com/dynamicindex3/snow.htm

I fill in the codes and it works but the snowflakes only go to 1/5 of the page. Is there a way I can get the snow falling on the whole page? This is the test board I did it on.

Thanks for any help you can give me.
