Variation Price Range function

Your theme author needs to add this, not you. It’s clear they are customising templates: https://dl.dropboxusercontent.com/s/wig97xvmd18bj10/2016-07-21%20at%2011.01.png?dl=0

if the range shows with the default 2016 theme, you’ll know it’s the theme ??

Thank you for your quick response.

Is it possible to update it in the latest version by me?

I can just replace the code with your latest updated variable.php file and if it is needed to add some code in the function.php.

Well i tried to replace it with the latest version of yours and it seems something is missing, cause there aren’t any changes.
So it might need a change in the function.php

/**
 * Road Themes functions and definitions

 * Sets up the theme and provides some helper functions, which are used
 * in the theme as custom template tags. Others are attached to action and
 * filter hooks in WordPress to change core functionality.
 *
 * When using a child theme (see https://codex.www.ads-software.com/Theme_Development and
 * https://codex.www.ads-software.com/Child_Themes), you can override certain functions
 * (those wrapped in a function_exists() call) by defining them first in your child theme's
 * functions.php file. The child theme's functions.php file is included before the parent
 * theme's file, so the child theme functions would be used.
 *
 * Functions that are not pluggable (not wrapped in function_exists()) are instead attached
 * to a filter or action hook.
