How to pass enum into a function that uses a switch case?

I have this block of code that declares an enum data type called "motorGroup"

I want to pass a value from this data type into a function that uses a switch case.

When I try this, I get the following error:

error: expected ')' before 'group'

How do I make it so that I can pass the enum into the actuatorPull function and have it be interpreted by the switch-case?

enum{TOP, BOTTOM}motorGroup; long pulses; int ppi = 0; int dist = 0; int speed; void pulseCount() { pulses++; dist = pulses / ppi; } void systemInit() { pinMode(4, OUTPUT); pinMode(5, OUTPUT); pinMode(6, OUTPUT); pinMode(7, OUTPUT); pinMode(8, OUTPUT); pinMode(9, OUTPUT); pinMode(10, OUTPUT); pinMode(11, OUTPUT); attachInterrupt(digitalPinToInterrupt(2), pulseCount, RISING); } void actuatorPush(motorGroup group, int speed) { switch(group) { case TOP: analogWrite(4, speed); analogWrite(5, 0); analogWrite(6, speed); analogWrite(7, 0); break; case BOTTOM: analogWrite(8, speed); analogWrite(9, 0); analogWrite(10, speed); analogWrite(11, 0); break; } } void actuatorPull(motorGroup group, int speed) { switch(group) { case TOP: analogWrite(4, 0); analogWrite(5, speed); analogWrite(6, 0); analogWrite(7, speed); break; case BOTTOM: analogWrite(8, 0); analogWrite(9, speed); analogWrite(10, 0); analogWrite(11, speed); break; } }
