Control.com - Nerds in Control

I'm new to using Unity Pro software, and as a part of my logic I use some FB to do some repetitive task like clamping, etc. But when I began the debugging interface I couldn't see what's happening inside that FBs, nor monitor private variables on the animation table...

Does anybody knows how this can be done?

I place all the code in a regular section and test it first. It's a pain but it's the only way I know of.
