Hi, Mohamed.

Thank you for reaching out!

Since the variable slide.ElapsedTime will change its value depending on which slide the user is currently viewing, you need to assign it to a different variable per slide.

I'm attaching a sample .story file with three slides (two that track the amount of time the user spends on the slide, and one results slide that calculates the total):

  • Slide 1: Set Slide1_Time (a numeric variable) to variable Slide.ElapsedTime when the user clicks the Next button.
  • Slide 2: Set Slide2_Time to variable slide.ElapsedTime when the user clicks the Next button.
  • Slide 3:
    • Add Slide1_Time and Slide2_Time to the numeric variable Total_Time
    • Set Total_Seconds to Total_Time
    • Divide Total_seconds by 1000 (converting the time into seconds)

Here are the variables used:

Hi, Mohamed.

I'm happy it worked for you!

If you want to display the time as minutes and seconds, you will likely need Javascript. I'm not very good with Javascript, but I found a few helpful discussions, like this one

I edited my sample file to execute a similar code, and it seems to work.
