Hello,
I am working on an XLSForm where I want to calculate the percentage of correct answers and categorize the result into three levels: High, Medium, and Low using the if() function in a calculation. However, when I upload the form to ODK Validate or XLSForm Online, I get an error saying: "Couldn't understand the expression."
Could you please help me by sharing a correct example or guide me on how to properly write this calculation?
Thank you very much for your support.
Best regards,
Faisal Amani
