[solved]Servo program won't compile

hi there folks,

i'm trying make device maker faire, got completed program has 1 mistake has attaching writing of servo. it's supposed point @ strongest lightsource through 2 ldrs, turning servo. down below code got it. problem quite obvious can't seem figure out. take @ , explain me i'm doing wrong?

code: [select]

#include <servo.h>
#define servo 9
#define leftsensor 0
#define rightsensor 1
#define button 2
#define led 13

servo servo;

int speed = 50;
int leftsensorval = 0;
int rightsensorval = 0;
int sensorthreshold = 200;
int delayparam = 10;
int buttonval = 0;
int old_buttonval = 0;
int buttonstate = 0;

void setup()
{
 serial.begin(9600);
 servosetup();
}

void loop()
{
 leftsensorval = analogread(leftsensor);
 rightsensorval = analogread(rightsensor);
 buttonval = digitalread(button);
 
 if((buttonval == high) && (old_buttonval == low))
 {
   serial.println("button pushed");
   buttonstate = 1 - buttonstate;
   delay(10);
 }
 old_buttonval = buttonval;
 
 if(buttonstate == 1)
 {
   digitalwrite(led, high);
   
   if(leftsensorval - rightsensorval >= sensorthreshold)
   {
     serial.println("left");
     goleft();
     delay(delayparam * 100);
     gostop();
   }
   else if(rightsensorval - leftsensorval >= sensorthreshold)
   {
     serial.println("right");
     goright();
     delay(delayparam * 100);
     gostop();
   }
 }
 else
 {
   serial.println("stop");
   digitalwrite(led, low);
   gostop();
 }
}

void servosetup()
{
 setspeed(speed);
 pinmode(servo, output);
 servo.attach(servo);
 pinmode(button, input);
 pinmode(led, output);
 gostop();
}

void setspeed(int newspeed)
{
 setspeedservo(newspeed);
}

void setspeedservo(int newspeed)
{
 if(newspeed >= 100) {newspeed = 100;}
 if(newspeed <= 0) {newspeed = 0;}
 speed = newspeed * 0.9;
}

void goright()
{
 servo.write(90 + speed);
}

void goleft()
{
 servo.write(90 - speed);
}

void gostop()
{
 servo.write(90);
}

it gives following error:

thanks have answer.

hi lenny

code: [select]

#define servo 9
...
servo servo;

you've confused poor program  

the first "servo" represents pin number.  the second servo name of instance of servo object.  one of "servo"s needs change.  probably quicker change former, , remember change wherever pin number appears parameter function call. example ...

code: [select]

#define servopin 9
