Jeez! Being battling with this theme named skyali for over

Hi,
Jeez! Being battling with this theme named skyali for over 4hours to create child theme and I've used all the skills I have but not working. Here is the skyali child theme stylesheet attached to the theme;
/*
Theme Name: Smooth Child Theme
Theme URI: http://londonthemes.com/index.php?themeforest=true
Description: Child theme for Smooth
Author: Skyali
Author URI: http://londonthemes.com/index.php?themeforest=true
Template: Smooth
Version: 1.0
*/

@import url("../Smooth/style.css");

/* ------- Insert custom styles below this line ------- */

And it showing this message in my theme area;
The following themes are installed but incomplete. Themes must have a stylesheet and a template.
Name Description
Smooth Child Theme The parent theme is missing. Please install the "Smooth" parent theme.
How can you aid me solve this?

Regards
