cursor_roi variable in JATOS/OSWeb
I am designing a simple number comparison task in which a child sees two numbers and needs to select the bigger number. We are planning to collect data using iPads by uploading our study to JATOS. I designed the task using a sketchpad and mouse response (so a child can click the number). My problem is that I am using the variable 'cursor_roi' to keep track of children's responses and whether or not they got the answer correct. However, I noticed that my inline script using cursor_roi does not work on JATOS/OSWeb. Is there a way to fix this/different way to keep track of children's responses and create a 'correct' variable that shows whether or not they got the problem correct?
Thank you all for your help!
