AFPHairrig v03.51 error de expresión

Tengo un error que ya se posteo en estos foros y algunos de reddit hace unos años, pero no encuentro solución y simplemente no puedo utilizar el script

Aqui dejo el codigo junto algunas capturas de lo que me sale:

/////AFPHairRig//////
if(thisComp.layer('MASTER_HR_controller').effect('TurnOffHairRig')('Checkbox') == false)
{

pointFromParent= 4;
refLayer = thisLayer;
pos = refLayer.effect('Delay')('Slider')*(pointFromParent/8);
fallOffLoc = (pointFromParent-1)/4;
amp = refLayer.effect('Amp')('Slider')*refLayer.effect('FallOff')('Slider').valueAtTime(fallOffLoc)*thisComp.layer('MASTER_HR_controller').effect('masterFallOff')('Slider').valueAtTime(fallOffLoc)*comp('GLOBAL_HR_controller').layer('GLOBAL_HR_controller').effect('globalFallOff')('Slider').valueAtTime(fallOffLoc);
freq = refLayer.effect('Freq')('Slider');
masterFreq = thisComp.layer('MASTER_HR_controller').effect('masterFreq')('Slider');
globalFreq = comp('GLOBAL_HR_controller').layer('GLOBAL_HR_controller').effect('globalFreq')('Slider');
offset =refLayer.effect('Offset')('Slider');
phase = refLayer.effect('PhaseLocator')('Slider');
delay = 1-(pos*(1/refLayer.effect('Freq')('Slider')));

n = freq.numKeys+masterFreq.numKeys+globalFreq.numKeys;
if (n > 0)
{
delay = (1-(pos));
};
value+refLayer.effect('WaveMath')('Angle').valueAtTime(time+delay)*amp;

}else
{
value;
};
