mathowie-
1) I wasn't quite as interested in this feature for importing data as I am for adding fillups. Calculating the columns is a 30 second operation in excel. But having the exact total from the receipt is more useful to me than price per gallon. If you disagree with me, I'll have to refer you to my wife who believes she keeps the checkbook.
2) Data archiving is the reason for this request. I don't know how long your site will be around, but my mileage data is important to me. If I can scrape this off the site with a script then I'll do that.
Again, these were just suggestions. No offence was intended. I did search the forum but found nothing. Perhaps my search terms were flawed. At any rate I appreciate the response.
