Ok, here is the problem.

Ok, I am trying to combine all the information I have been given. I tried to make things clearer. I am getting this error now:

'pingRange' was not declared in this scope

Here is a current copy of the program. Thank you all for the help. I have a few h bridges I could use but I don't feel I would learn as much that way. Besides I saving them for a build up of this project once I grasp a better understanding of what I'm doing.

#include <Servo.h> 
Servo myservoA;  
const int pingPin = 7; 


void robotRight()
{ 
   if (microsecondsToInches(pingRange(pingPin)) < 10) 
  
    myservoA.write(90);
    delay(1000);
  } 
  else
  {
    myservoA.write(0);
  }
}




void setup() 
{ 
  myservoA.attach(4);   
  delay(5000);
  myservoA.write(0);
  Serial.begin(9600);
  
} 


void loop() 
{ 

  
  unsigned long pingRange (byte pingPin) 

  pinMode(pingPin, OUTPUT);
  digitalWrite(pingPin, LOW);
  delayMicroseconds(2);
  digitalWrite(pingPin, HIGH);
  delayMicroseconds(5);
  digitalWrite(pingPin, LOW);

  pinMode(pingPin, INPUT);
  return pulseIn(pingPin, HIGH);
}


long microsecondsToInches(long microseconds)
{
  return microseconds / 74 / 2;
}
