Solution:
I went through the snapshot that you have posted. Error was “Page does not contain the shortcode”. Now, I think you have created and set the checkout page but have not used woocommerce checkout shortcode on the page. So, paste the follwoing shortcode of woocommerce on the checkout page.
[woocommerce_checkout]
