Help please: Servo Library Error

I ran this code, and it seemed to have some errors about variables. Can you explain to me, please. Here, I am basically controlling different servo, using wireless communication through Xbee. So, once the code receives the serial, it will map, and assign the value to the variable. Once it is done, it will continue to the next value. Now, just for testing I only have two servo actually working but why are there an errors in this Could you please help, please.

#include <Servo.h>

Servo Sample, a,b,c,d,e;

int pin=13;


void setup() {
  // put your setup code here, to run once:
Serial.begin(9600);

Sample.attach(13);
a.attach(12);
b.attach(11);
c.attach(10);
d.attach(9);
e.attach(8);
}

void loop() {

int ValSam = Serial.read - "0" ;
ValSam = map (ValSam, 0, 9, 60, 90);
int Vale = Serial.read - "0" ;
Vale = map (Vale, 0, 9, 60, 90);


Sample.write(ValSam);
a.write(0);
b.write(0);
c.write(0);
d.write(0);
e.write(75);
}
int ValSam = Serial.read - "0" ;

No brackets on Serial.read() No check whether there is actually anything to read You are subtracting a string literal rather than a char

Thank You? Why do I miss so easy stuff? Thank You Again! :) :) :)

The error has nothing whatsoever to do with the Servo library.
