issue on creating child theme

I want to create a child theme. But my parent theme is different from the child theme. Parent theme and child theme have 2 different styles. The parent theme is the LeadEngine theme and the child theme is Ave theme. Here is my child theme style.css file.

/*
 Theme Name: Ave Child
 Theme URI: http://ave.liquid-themes.com/
 Author: Liquid Themes
 Author URI: https://themeforest.net/user/liquidthemes
 Template: leadengine
 Description: Smart, Powerful and Unlimited Customizable WordPress Child Theme.
 Version: 2.7
 License: GNU General Public License
 License URI: license.txt
 Text Domain: ave-child
 Tags: responsive, retina, rtl-language-support, blog, portfolio, custom-colors, live-editor
 */
  @import url("../leadengine/style.css");

And after this code, there is child theme style code.
Here is my function.php file.

/**
 * The Liquid Themes Ave Theme
 *
 * Note: Do not add any custom code here. Please use a child theme so that your customizations aren't lost during updates.

 // Starting The Engine / Load the Liquid Framework ----------------
 add_action( 'wp_enqueue_scripts', 'enqueue_parent_styles' );

 function enqueue_parent_styles() {
   wp_enqueue_style( 'parent-style', get_template_directory_uri().'/style.css' );
 }
 include_once( get_template_directory() . '/liquid/liquid-init.php' );

But it is showing an error.
