Help styling a button

[itsalltech]

I am trying to CSS a button on my website, http://www.itsalltech.com. However, everything works, but the background image of the button does not show up. I've added the CSS in the Stylesheet and uploaded the images into the correct path. Also, I've checked the path of the image in the stylesheet. Any ideas? Thanks.

I probably should have posted back. For some reason, the path to that image was not working. I chose another image and everything is working.
