I realized the per gallon price was being displayed instead of the total price so had to go back and edit my data and now it's not working again even though I did all the same steps to make it work before

I was able to get it working by 1) Creating this macro in Excel to export the CSV with quotes http://support.microsoft.com/kb/291296/en-us and then 2) deleting line breaks. Fuelio still crashed when I imported it, but once I reopened it my data was all there.
