Default Variable Values

So in my coming game, I am working on a sort of Approval/Trust system with each of your partners throughout the journey and so the main idea for this was each partner that joins starts with a default of 50 points (Out of 100) in the approval/trust system (Based on your decisions, etc.). My question is, how do I set this default? The issue is, I want to make it so when the partner hits 0, they have a small script and ditch the party, so I need the value to be set at a default 50 right as they are added to the party. Is there a way to do this?

You use an autorun event on the first map with a series of control variable commands setting the starting values for any variable where you need a different value than zero.
Don't forget to switch off the autorun after that.
