Help needed with this script

[DaffyDuck]

Hello everyone

Im trying to add a "Open new browser window (on click) script" to one of my web pages and i have found the following script

<a href="about-us.htm" onclick="window.open(toolbar=1,resizable=0,status=0,menubar=0,scrollbars=1) ;return false;">Open in new window</a>

But there's something wrong with it as it gives a 404 error page with a long URL consisting

toolbar=1,resizable=0,status=0,menubar=0,scrollbars=1 on the URL

Can anyone check wots wrong with is script and give me the right format

Thanks

onclick="window.open(toolbar=1,resizable=0,status=0,menubar=0,scrollbars=1)

SHOULD BE

onclick="window.open(http://www.example.com)
