How do I Trade Variables? [Solved]

Okay, I feel this should be easy but for the life of me I can't figure out how to properly do it.

I'm looking to make it so that you can hit a Reset button and all the points you have spent will be refunded and they will be added back to points available.

My approach is creating two Global variables:

-PointsSpent

-PointsAvailable

Whenever they add a point to their stats, +1 to PointsSpent and -1 to PointsAvailable.. got that.

But when they hit reset, how can I make it so that I take all the Points Spent and add them to Points Available and then afterwards, put PointsSpent to 0?

EDIT: Solved it.
