Hi Jeremy,
Thank you for your tips! The second question was perfectly solved.
However, the regular expression under the command test.text() failed to regulate the input in my experiment.I tried what you recommended but no matter what I entered, even Chinese characters, the experiment went on without any warning or pause. I was thinking it might need a confirmation command as well so I also tried .wait() after test.text() but it still didn’t work.
Here is the demonstration link to the pilot experiment.
I would appreciate it if you could give me some more advice!
Best,
Muxuan
