Issue in Country Change and Price and Need Variable Option as shown in screensho

Hello,

You have not provided your screenshot.

The issue of Countries. If you mean countries in the checkout, this option is configured in Woocommerce > Settings > General options.

Here you will find instructions on how to set the prices for each variation: https://docs.woocommerce.com/document/variable-product/

If you have different prices for variations, the price will be displayed as a range. This is Woocommerce functionality and our theme does not influence that.

Best Regards
