I'm working to insert my own VAR into an existing template. I've seen the examples saying to use vb_Template:

reRegister. However I have a catch...I'm using a cloned copy of an existing template. For example, I cloned the default style -- and created newStyle. Then within newStyle, I modified postbit_legacy and would like to display my own $var within the cloned copy of postbit_legacy.
Questions:
1. How to register/preRegister into a cloned template (newStyle->postbit_legacy).
2. How to properly use preRegister -- if that's what's needed. My data isn't an array, and preRegister only works with arrays.
