Adding or Sum of Variables. Possible?
I'm making a simulation type game in storyline which has branching to different paths based on 3 different choices.
I made a variable called "Money from Company A", and i want this to be updated based on a given choice.
So let's say for simplicity:
Choice 1 - 10$
Choice 2 - 5 $
Choice 3 - 1$
If we have 5 questions in total, the maximum score should be 50$, and the minimum 5$, with a bunch of other possibilties.
The problem i was encountering was when a user is on the screen, and selects choice 1 then changes their mind to choice 2, the triggers i have set still add the points up. So a user can get more than 10$ on a question if they keep switching between choice 1 and choice 2.
I overcame this by making the variable change only when the user clicks the "submit" button at the end, so they have left the slide, and cannot change their answer.
All good up until this point.
But I was wondering whether or not I could calculate the sum of different variables, if I decided to add another company into my scenario? So in the results slide, I could show a total of the money earned from the two companies.
is there a function that could do %Money from A% + %Money from B% ? Or Sum(Variable1, Variable2)?
The only solution I have now, is to display the two variables in the results slide, and have the person add it up manually.

Thanks guys and girls, I've found this post very helpful!
Glad that this older post was able to assist you as well Mimi :) Thanks for popping in to share.
Thank you, Phil, your example file was such a time saver!

Hi Susan,
As DANIEL said, it's tedious!
Your javascript doesn't add variables, but just put them close together (1+2=12).
Adding variables feature should be essential.
Hi Rozbud,
This discussion is a bit older, and Javascript isn't something I can help with - but can you share a bit more about what you'd like to see for variable features I'd love to get those ideas in the hands of our product team!
I sorta done a work around for this, I made a bar where it totals up your drinks. http://www.alcoholandyouni.com/unitchecker/story_html5.html I used the scores from the variables to change another text box with the score? It even can connect to a database with your results. I'm actually making another tonight and looked here to see if there is a better way?
Exactly what I was looking for. Thanks a lot Phil!
Mary,
Phil's example adds three variables (Money1, Money2, and Money3) together. To add more, just duplicate either of the circled triggers, and use the appropriate variable.
Even 11 years later this gift keeps on giving. Thank you Phil! Bless you sir.
