Can't display calculated items

I'm trying to display calculated items using Responses.xls. For some reason, MediaLab doesn't show the calculated score from the excel file. Am I doing something wrong? I attached the files.
I'm working on Mac with Paralells and I hope that's not the problem...

Hi Eyal --

It would seem that the problem you're experiencing resolves itself if you remove all upper-case lettering from within your responses.xls file and the variable names within your questionnaire.

ie.
Rather than Truck50, Truck60, Truck70, and TruckScore -
Use: truck50, truck60, truck70, and truckscore

Thanks! that worked!
