ClickBank Analytics Help

Okay, so I've had some clicks on my CB links via my blog. I had about 7 form impressions and over a hundred hops after a mere few days. I see a 1 in the #Order Form Server Calls. I guess this mean one person has attempted to buy. However, I don't see any sales in the Initial Sales count. Does this mean the user might have chickened out after clicking the "BUY" button?

Not quite sure what the #Order Form Server Calls means. Help is welcomed

chickened out, or some problem with how they want to pay
