child theme installation problem

Hi,
I am trying to install child theme of Geotheme. I am getting the following error.
“Name Description
GeoTheme – Child Theme
The parent theme is missing. Please install the “GeoTheme” parent theme.”

Although after reading a number of forums. I made sure that the child theme and parent theme exist parallel and also the style.css in child theme contains the exact name of the parent folder for template attribute and @import.

this is how it looks like.
/*
Theme Name: GeoTheme – Child Theme
Theme URI: http://www.GeoTheme.com/
Description: Child Theme for GeoTheme V3
Author: GeoTheme
Author URI: http://www.geotheme.com/
Template: GeoTheme_3.4.5
Version: 1.3.4
*/

@import url(“../GeoTheme_3.4.5/style.css”);

please let me know what am I doing wrong?
