CrossRoads:
Compiler tells you the problems.

switchpin is not the same as switchPin.. C++ is case sensitive.

byte run; is missing

You're missing a } at the end.

Thank you, I didn't have my screen setup properly to see that.

I have reverted to a simpler code shown below. It does not revert back to "OFF" after the timer, where am I going wrong here?

int ledPin = A5;
int switchPin = A0;
boolean lastButton = LOW;
boolean currentButton = LOW;
int switch2Pin = A1;
boolean last2Button = LOW;
boolean current2Button = LOW;

void setup ()
{
  pinMode(ledPin, OUTPUT);
  pinMode(switchPin, INPUT);
  pinMode(switch2Pin, INPUT);
}

boolean debounce(boolean last)
{
  boolean current = digitalRead(switchPin);
  if (last != current)
  {
    (delay(5));
  }
  return current;
}

boolean debounce2(boolean last2)
{
  boolean current2 = digitalRead(switch2Pin);
  if (last2 != current2)
  {
    (delay(5));
  }
  return current2;
}

void loop ()
{
  current2Button = debounce2(last2Button);
  if (last2Button == LOW && current2Button == HIGH)
  {
    /*
     * Here is where the static flow is. currently set to 
     * 10 seconds of on time. This will need changed for 
     * different flow rate injectors so you dont overfill
     * your graduated cylinders.
     */
    delay(500);
    digitalWrite(ledPin, HIGH);
    delay(2000);
    digitalWrite(ledPin, LOW);
  }
  
 
  
  
  
}
