there is no image attached unfortunately. However, from your private message I get the error you're receiving is "Yp2 ist kein gultiges datum" what translates to "Yp2 is not a valid date". I'd therefore recommend to check the date format in the file as well as in the settings.
Dear sir Please find the attached SVF file and Input data . There is some error in PET calculation. All the files are attached along this post. Kindly suggest where the mistake is.
