Digit in sketchpad and feedback item gives js error t.replace
in my Osweb experiment I used a sketchpad in which an image and text (digits (eg 1,2,3) for a scale) are presented simultaneously.
This is not working. I have to add a letter to the number in order to make it work.
I tried also with a feedback item, but gave me the same following error.
Uncaught TypeError: t.replace is not a function
Do you have any suggestion?
