Solve the following python programming problem given the following code:
def trigger(self, ui) : 
    '
        Trigger this animation
        ' 
    damage_counter = DamageCounter (damage = str (self.damage), colour = self.colour, parent = ui) 
    ui.view.scene ().addItem (damage_counter) 
    damage_counter.setZValue (zorder_counter) 
    bounds = damage_counter.boundingRect () 
    width = bounds.width () 
    rand = Random () 
    damage_counter.setPos ((((((self.location [0] * 32) + 16) - (width / 2)) + rand.randint ((- 16), 16)) + self.offset [0]), ((self.location [1] * 32) + self.offset [1])) 
    animation = QSequentialAnimationGroup () 
    moving = QPropertyAnimation (clean_up.adapter, 'y_location') 
    moving.setDuration (750) 
    moving.setStartValue (((self.location [1] * 32) + self.offset [1])) 
    moving.setEndValue ((((self.location [1] * 32) - 32) + self.offset [1])) 
    curve = QEasingCurve (QEasingCurve.OutElastic) 
    moving.setEasingCurve (curve) 
    animation.addAnimation (moving) 
    fading = QPropertyAnimation (damage_counter.adapter, 'opacity') 
    fading.setDuration (750) 
    fading.setStartValue (1.0) 
    fading.setEndValue (0.0) 
    animation.addAnimation (fading) 
    def clean_up() : 
        animation.stop () 
        ui.animations.remove (animation) 
        ui.view.items ().remove (damage_counter) 
        ui.remove_finished_animation () 
ui.animations.append (animation) 
    animation.start () 

    
    

    Fix the buggy line: moving = QPropertyAnimation (clean_up.adapter, 'y_location')
