PWM to controll the fan(12 dc motor with driver) using 16f877a and lm35***help plz***

Hi everyone
in my project I want to increasing the speed of dc motor according to the temperature , I have found some sample source I try to modified it but it does not working (simulated with Proteus)
here is the code :
#define alarm RC1 // activate as fan but I put led for this part
#define motor RC2//DC motor activate as fan


unsigned char speed=50;


//////////////////////SET PWM//////////////////////////////////////

CCP1CON = 0b00001100; //PWM Mode
PR2 = 0xFF; //PWM Period Setting//PWM frequecy set as 4.88KHz
T2CON = 0b00000101; //Timer2 On, prescale 4
CCPR1L=0;

f(temperature>27)// when the temperature goes above the 27 degree C the fan activated otherwise the fan is deactivated
{
alarm=1;
}


else if (temperature>30)
{

while(temperature>30)continue;

CCP1CON = 0b00001100; //PWM Mode
PR2 = 0xFF; //PWM Period Setting//PWM frequecy set as 4.88KHz
T2CON = 0b00000101; //Timer2 On, prescale 4
CCPR1L=speed; }




/* else if (temperature<27)

{
CCPR1L=0;
}*/





/*else if (temperature>35)

{
if(speed<255)speed+=1;
CCPR1L=speed; // INCREMENT THE SPEED OF MOTOR
delay(5000);
}

else if (temperature<35)
{
if(speed>0)speed-=1;
CCPR1L=speed; // DECREMENT THE SPEED OF MOTOR
delay(5000);

}

plzzzzzzzzzz help

actually while I write CCPR1L=0; then it does not work at all ? i dun know why ?

any advice ?



thanks everyone

here is the main code which I have tried to modified it :

//==========================================================================
#define BUTTON1 RA1
#define BUTTON2 RA2
#define BUTTON3 RA3
#define BUTTON4 RA4
#define CCW RB1
#define CW RB2

// function prototype

void delay(unsigned long data);

// global variable
unsigned char temp=50;

// main function
//==========================================================================
void main(void)
{

ADCON1 = 0x06; //Configure Poart A as digital I/O

TRISA = 0b11111111; //Set pin RA1 to RA4 as input for press button switch
TRISB = 0b00000000; //Set pin RB1 & RB2 as output for MD10A
TRISC = 0b11000000; //Set pin RC2 as output for PWM

CCP1CON = 0b00001100; //PWM Mode

//PWM frequecy set as 4.88KHz
PR2 = 0xFF; //PWM Period Setting
T2CON = 0b00000101; //Timer2 On, prescale 4

//Motor stop
CCPR1L = 0; //No PWM Duty Cycle
CW = 0;
CCW = 0;

while(1) //Infinity Loop
{
if(BUTTON1==0) //Brake
{
CCPR1L=0;
CW=0;
CCW=0;
}

else if(BUTTON2==0) //Change the Rotational Direction
{
while(BUTTON2==0)continue;
CCPR1L=temp;
CW=!CW;
CCW=!CW;
}

else if(BUTTON3==0) //Speed Increment
{
if(temp<255)temp+=1;
CCPR1L=temp;
delay(5000);
}

else if(BUTTON4==0) //Speed Decrement
{
if(temp>0)temp-=1;
CCPR1L=temp;
delay(5000);
}
}
