This is what I found for error 240
It does not seem to fit with what you are selling at the moment.
Error Code 240: The item cannot be listed or modified. The title and/or description may contain improper words, or the listing or seller may be in violation of eBay policy. Alert: To sell baby formula on eBay, you need to specify the expiration date (mm/dd/yyyy) and include the following text in your listing: This baby formula is not expired – the expiration date is mm/dd/yyyy. It's against eBay policy to sell expired baby formula.
