Open SWF In New Window

I know how to open a new browser window with javascript. But I tried to set the path to an swf file I have on the server and it didn't work. I tried just the file name, and the full internet path. Anybody know whats wrong?

How did you tried to open a new browser window with javascript?

VB Code:

function openwindow()
{
window.open("http://www.geocities.com/mushroomrealm/kristenstar.swf","my_new_window","toolbar=no,location=no,directories=no,status=no,menubar=no,scrollbars=no,resizable=no,copyhistory=yes,width=400,height=400")
}
