Error:

- Error Code 197:

Short Message - Listing in multiple categories is not supported. 

Long Message - To list in 2 categories, please specify 2 different categories.



Explanation and Resolution:

This error is usually triggered when the exact same category value has been set for Category ID and at the same time for the Category ID2 field. Click on the blue Show second category button in the UI, so the second category field would expand and both be visible and remove the duplicate value from the second field or put another different value for the secondary category in case the item needs to be listed in multiple categories before re-listing the item and re-submitting it to eBay.
