Result slide query

Hi All

I have downloaded one of your gamified template from the resource links.

However, there is just one issue I am facing while using the template.

I have changed the game content with two categories, and the two team members will then need to select either category 1 or category 2 which has respective questions on it.

The result slide which is the (Total score) on the template would then need to calculate the total score of category 1 and category 2. I'm finding it difficult to make the result slide were the addition of category 1 and addition of category 2 is made.

Please find attached my storyline file.

Kindly look into my file and please let me know what is the solutions for this.
