I am creating the child theme as indicated
the style sheet in the child them reads as follows :
/*
Theme Name: Twentyten-child
Theme URI: http://chekpeds.com/
Description: The 2010 modified for Chekpeds.
Author: c.berthet
Author URI: http://chekpeds.com
Template: twentyten

*/

@import url(/twentyten/style.css);

When doing so I get a Broken theme message saying the template cannot be found – install “twentyten\”

When I do it, here is the message I get
“Broken Themes
The following themes are installed but incomplete. Themes must have a stylesheet and a template.
Name Description
Twentyten-child\ The parent theme is missing. Please install the “twentyten\\\” parent theme.”

I Modify my template line to twentyten\\\
and it comes back with the same message asking to install “twentyten\\\\\\\”

I have style.css is the only file i Have in the childl directory

can you please help?
