You can use Variables for your Logic and calculations to add up scores or prices. You can also create your own custom Variables.
1. Go to the Logic panel, select Advanced then Variables:
2. Now you’ll see the default Variables. Click + Add variable to create your own, then hit Save when ready.
You’ll always see the price and score Variables in the list, but they are greyed out by default. The price Variable will become available when you add a Payment question to your typeform, and the score Variable will become available when you add scores.
