Could not add this item 2F332567886702(2).

[Rafo000]

Won’t add any item I want to snipe.

2F332567886702
2F302649778539

Just two item numbers as an example but it won’t add any items at all.

[Cupid]

Where did you pick these numbers up from?

Neither of them are auction numbers, that's why you can't add them.

Auction numbers are 12 digit numbers found at the top right of the description, on the Ebay item page, they are labelled as 'eBay item number:'.

I think, perhaps, you need to loose the '2F' you have appended to the front, do you know why you have that ?
