title: Psychopy builder expt. - how to add live updating text on screen
body: <p>I am creating an experiment using Psychopy builder.
  The participant is presented with an image containing numbers, e.g. 10 and 20.
  They enter what they think is the mean of the numbers, 15 in this case, and then press the spacebar to move on to the next image.</p>
  
  <p>I am trying to have it so there is a display/box on screen that shows them their entry, as with larger numbers in the hundreds of thousands and millions I think they might lose track of what they have pressed. 
  The ability to change their entry would be excellent also, but really I am most interested in them being able to see it on screen.</p>
  
  <p>In builder I can't find a way to do this, and the ratings scale is not appropriate for huge numbers. </p>
  
  <p>I found these solutions in code to do something that sounds like it:

  <p>However when I try to add them using the code insert function , or just adding them to the compiled script the screen locks up when I try to run the experiment. I am a novice at python, and am not sure where to start fixing this. Is what I'm trying to do possible?
  I'm happy to provide some example code from the compiled builder experiment.
  Thanks in advance!</p>
