I have updated the sheet and deleted
Theme URI: http://www.gavick.com as apparently Theme URI it is not required. The only thing I would add is that the site is currently sitting on a subdomain.
Below is an example of a working child theme on the same site. This style sheet works fine. A little observation here is that the theme folders do not have any capital letters.
