  Hi @m2o ,

  
  

  Thanks for your interest in OpenSesame and welcome to the forum! :)

  It sounds like something goes wrong either when you define the variables for the x coordinates for the target or the distractor, or when you are trying to use them.

  
  

  Could you check:

  • The loop item (in the tutorial called the "block_loop") where you define the variables "target_pos" and "dist_pos". Are you sure all the cells in these columns filled with numbers? Aren't there any empty rows, for example at the end of the table? If so, you should remove them
  • The sketchpad item where you use the variables "target_pos" and "dist_pos". Are you sure you are using the square-bracket syntax to define the x coordinates correctly, like so?

  For the target letter:

  draw textline center=1 color=black font_bold=no font_family=mono font_italic=no font_size=32 html=yes show_if=always text="[target_letter]" x=[target_pos] y=0 z_index=0
  

  
  

  And for the distractor letter:

  draw textline center=1 color=black font_bold=no font_family=mono font_italic=no font_size=32 html=yes show_if=always text=X x=[dist_pos] y=0 z_index=0
  

  
  

  If these tips don't solve your issue, could you upload your osexp file here (by clicking the paperclip icon)? Then I'm sure we can help you.

  
  

  Cheers,

  Dear Lotje,

  Thank you very much for your quick comments. I tried your options, but it did't work. I am sending you my osexp.

  Thanks in advance

  Hi @m2o ,

  
  

  Thanks for the script! You're almost there. The only thing is that, for some reason, the x coordinates of the text elements in the feedback display got lost (see screenshot below). If you set the x coordinates to something else (0, for example) your script should work. Good job!

  

  
  

  Cheers,

  Thank you very mach. The experiment runs now. However, I have 2 problems:

  1) The sounds works every answer when I run the program in my laptop, but there is no sound if I run the experiment in a browser.

  2) The accuracy result is always 'undefined ' when I run the experiment in my laptop and 0 in the browser.

  Hi,

  I was able to solve the accuracy result. I wrote 'correct_response' instead of 'correct_resp' in the loop_block. I solved the sound problem.

  Thank you very much for your help

  I am using gaze tutorial template in a experiment about percentages perception. I am having the same problem with 'acc' variable.
