Difference between sales ($) and transactions ($)?

[supersavingsstore]

Hi,

I though that I had met the requirements to qualify for Powerseller status and after many calls with eBay I was finally told I hadn't.  I am going to put some screen shots of my dashboard showing my sales and then my sales in the other section of the site. The thing is both are giving different information. The person on the phone told me that one was transactions and one was sales. The thing is though one shows significant less sales in terms of dollar amounts. Can anyone figure out why this is? 

Thanks, Adam
