submit button – close window and no redirect?

Hi

This is the code I have to make my subscribe pop-up close without going to a thankyou page. It doesn’t work, but I feel like it should. Do you know why it doesn’t work and if so can you let me know, please?

URL is [url]www.chaserbrand.com[/url]

Thanks!
phil
