Using Numbers and Variables in Storyline you can calculate almost anything. Only limitation is that SL rounds Numbers. If your calculation gets complex its better to use Javascript. Storyline rounds Numbers to 2 digits.
It's easier to do it with Javascript, but if that's not something you like to use, here's a workaround (example attached)
1. Add a numeric entry field 2. Create 3 additional variables, one for each percentage 3. Set all 3 variables to match the user's entry and to open up a new layer 4. Create a trigger to set new values for each of the three variables when the timeline on the new slide reaches 0.1 5. Staying on the new slide, add a box over the variables, which disappears quickly. Hide the layer once the box over the new variables has disappeared. Set this layer to always reset to initial state.
