Auto Numbering

First time I've messed with this. When I plugged in the csv file into the blueprint, I got this error: Input string was not in a correct format.
The numbers for the car were done with a MS Excel spreadsheet and was inputted correctly, IE 0 0 100. I've tried saving the file as a CSV (Comma delimited) and as a CSV (MS-DOS) and get the same error. How should it be saved and if I've done this right, were could my problem lie?
