Drawing Application in Vuforia

Hey guys, I really need some help with this application I'm making. I'm using this tutorial but a few things are going wrong:

To begin with, the application isn't picking up my flat "Image Target", only the cube that I'm using as a pen. This means that the objects generated by the pen aren't acting as children to the image target and are being drawn directly to the screen. I'm also having an issue where the prefab used for the pen is being cloned repeatedly and causing the app to lag and crash.

 

Any help is greatly appreciated!
