Hi rainbow,
When you choose the "hidden" version of the Sellathon counter, neither you or your customers will be able to see the counters in your listings themselves. However, you will be able to see the number of hits your items have received by looking in the "Hits" column on your Auctiva Active Listings page.
If you choose the "visible" version of the Sellathon counter, a graphic counter will be displayed at the bottom of your listings that either you or your potential buyers could read the hit counts from.
If you have any additional questions or concerns, please feel free to contact our customer support team using the web form on the following page of our site: http://www.auctiva.com/help/requesthelp.aspx
