vizzy and funkytree

i launched the missile and lock the target . however, the rotator doesn't work untill the missile were controlled by player.
the inputcontroller's input of Rotator is a variable of vizzy.

another problem is also about the vizzy and funk
I wrote an funky expression in vizzy and i wrote the same expression by vizzy code. the value of this two expressions are equal. but only the vizzy expression can be used.
you can view this two expressions in red part and blue part
