# I keep getting the error: "Option values provided for 1 unknown option(s)"

The reason why some products cannot updated is because some products didn't have the value for the variant option 1.![](https://storage.crisp.chat/users/helpdesk/website/b219050a5836c000/screenshot-2024-12-11-at-12141_12k0wk3.png)

This error occurs when variant option 1 is empty and variant option 2 has a value. 
  
**Reason**

* The reason why some product cannot updated is because of some products didn't have the value for the variant option 1.

 **Solution**

* To resolve this issue, you should switch the mapping column from option 2 to option 1.
