Hi gibsonbk,
Thanks for helping to bring this to our attention. The reason you are seeing these errors is because eBay seems to have made a change to their "view item" page that has caused the counters to stop working consistently. Our engineering team is working on a new version of the counter but it may take a couple days to get the issue resolved.
Fortunately, the Sellathon counters are currently set up so users won't have to update the counter code in their listings when we create a new version of the counter. There was a time in the not too distant past when that would have had to happen.
