Question AR Vuforia - Scale Model on Image Target Detection

Hi all,

I have an interior in AR and was wanting it to scale from a 2d plane to 3d object on the y-axis exactly how the guy does it in this video:

All of my models are attached to an empty object that is used for scale and location. I just need to scale the game object from 0.01-1 on the y-axis when the Image target has been detected. I can actually already achieve the desired effect in the viewport manually, but have no coding ability to be able to implement this at game time. Are there any coders out there willing to write this bit of script for me so I can learn how it is done?

Thanks,
Sam
