  Hi Asma,

  If you want to have three sliders running sequentially, you will have to make sure they do not run at the same time. The script below should run through three sliders, storing their filling percentage one by one.

  # import everything we need
  from openexp.canvas import canvas
  from openexp.mouse import mouse
  
  # create the instances we need
  my_canvas = canvas(self.experiment)
  my_mouse = mouse(self.experiment, timeout=20)
  
  # slider dimensions
  slider_w = 500
  slider_h = 10
  slider_x = self.get("width")/2 - slider_w/2
  # three different y-coordinates, one for each slider
  slider_y = [self.get("height")/4, 2*self.get("height")/4, 3*self.get("height")/4]
  
  # variable names to store the slider fillings in
  names = ["slider_1", "slider_2", "slider_3"]
  
  # questions to put above the sliders
  questions = ["question 1", "question 2", "question 3"]
  
  # loop through all three slider positions, to draw the empty slider canvas
  for i in range(len(slider_y)):
      # draw some text (this can be anything)
      my_canvas.text(questions[i], y=slider_y[i]-100)
      # draw the slider frame
      my_canvas.rect(slider_x, slider_y[i], slider_w, slider_h)
  
  # add a text below the bottom slider, telling participants to click to accept
  my_canvas.text("Click to accept ...", y=slider_y[-1]+100) 
  
  # loop through all three sliders, waiting for input
  for i in range(len(slider_y)):
  
      # keep showing the interactive slider until a click has been made
      clicked = False
      while not clicked:
  
          # determine the slider fill based on the mouse position
          pos, time = my_mouse.get_pos()
          x, y = pos
          slider_fill = min(slider_w, max(0, x-slider_x))
  
          # draw an empty rect within the slider frame, effectively resetting it
          my_canvas.rect(slider_x+1, slider_y[i]+1, slider_w-2, slider_h-2, fill=True, color=self.get("background"))
          # draw the slider fill
          my_canvas.rect(slider_x+1, slider_y[i]+1, slider_fill-2, slider_h-2, fill=True)
          # show the updated canvas
          my_canvas.show()
  
          # Poll the mouse for buttonclicks
          button, position, timestamp = my_mouse.get_click(timeout = 20)
          if button != None:
              clicked = True
  
      # save the slider's filling
      slider_percent = 100.0*slider_fill/slider_w     
      self.experiment.set(names[i], slider_percent)
  

  Good luck!
