satreasure on "Problem installing a Customizr Child Theme"

I am trying to install a Child theme so that I can make changes in Customizr. I used the instructions at this link: https://managewp.com/how-to-create-a-child-theme

The code in my child theme is:

/*
Theme Name: Customizr Child Theme
Theme URI: http: //themaverickedge.com/
Description: This is a custom child theme I have created.
Author: My Name
Author URI: http: //themaverickedge.com/
Template: Customizr
Version: 0.1
*/

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

But when I go to: Appearance => Themes to install the Child theme, I see an error at the bottom saying:

The parent theme is missing. Please install the "Customizr" parent theme.

Don't know what to do.

Please advise.
Thanks
