.join doesn't work in pavlovia

Hi @Yiannis, thanks again!

this works to some extent. Unfortunately it’s not possible now to delete the characters in case the participant would like to change their answer. Do you know how to include this?

I’ve tried to include “backspace” as allowed key for the keyboard component:

plus some code like this:

if len(textbox.text) > 0 and key_resp.keys == 'backspace':    
    textbox.text = ""
elif key_resp.keys:    
    textbox.text = "".join(key_resp.keys)

However, now when I hit backspace, it just prints “backspace” next to the numbers I just put in.
