Turret behavior, won't rotate towards target?

I have an object with the turret behavior, and I've changed

between assigning a target with both 'acquire target' and 'add object',

with different objects, and different ways to activate the script from

keyboard buttons to 'start of layout',

however the turret object never rotates?

By the descriptions of it's properties, i.e. 'turret rotation' and

'predictive aim' I would assume it should...however, it simply isn't?

Am I suppose to do some additional step besides targeting an object?

I'd really appreciate some help with this,

nothing ever seems to function for me =_=;
