Hi, Suma -- Thanks for your question and welcome to the community! Unfortunately, I am not equipped to provide support on JavaScript coding, however, I did want to provide this information on JS Best Practices so you have it handy. I know we have lots of JS gurus in the community, so hopefully, someone will be able to chime in to assist you further! :)

Hi Suma!

I think it works if you'll write the last line:

player.SetVar ("s", sum);

In your code the variable "s" gets the value "sum" !

I agree with Sebastian. Also, I don't quite see the need to use JS to add two Storyline variables and store the result in a third SL variable. You can do that with triggers.
