Resetting one variable to initial state

Hello,

I have built some variable driven scenarios in Lectora X.4. I have the scenarios placed in 3 different spots in my training so pulling from one variable has been great. I came up with an idea to allow participants to edit the scenario and come up with their own. I was able to get this done. The only problem is that I want them to have the ability to reset the variable to it's initial state and initial scenario. The only option I see is Reset All Variables. I don't want to use this because I have other tracking needs. Does anyone know of a javascript or something I can put in the value field to reset just one variable??? I know it should be an easy fix and I am drawing a blank.

Thanks!

Jeff
