Title: Clone function isn’t working Last modified: September 11, 2022 --- # Clone function isn’t working * [adamauskas](https://wordpress.org/support/users/adamauskas/) * (@adamauskas) * [3 years, 9 months ago](https://wordpress.org/support/topic/clone-function-isnt-working/) * Hello! I am using WC Fields Factory for Variation fields. And I have quite massive group of fields which needs to be cloned and mapped to different kind of product variations. * But then I click on the link “Clone” (under the name of groupd field) – page reloads and nothing changes. There are still no any new cloned group fields. * Can you please help me to understand what I am doing wrong? I will be very grateful!
