Spi commuication using pic and mikroc

HI
PLEASE HELP ME
I am an engineering student trying to learn SPI communication using pic16f877a and mikroc compiler.I wrote 2 codes one for pic spi master that continuously sends digit 3 and another code for pic spi slave that listens to master and makes the RB0 pin high if digit 3 is received.When i simulated it on proteus7.1 i could see the state change of SCK pin and SD0 pin of spimaster but nothing happend at the slave side. i am giving my codes below,please point out the bug or give me some sample code for both master and slave in mikroc.please help me
project settingsfor both master and slave)
mikroc v 6.2.1.0
microcontroller:16f877a
configuration settings default
clock frequency 12mhz
// code for spi master
void main()
{
Spi_Init_Advanced(MASTER_OSC_DIV64,DATA_SAMPLE_MIDDLE,CLK_IDLE_LOW,HIGH_2_LOW);
while(1)
{
Spi_Write(3);
}
}
// code for spi slave
void main()
{
unsigned char buffer,gdata=0x00;
buffer=0x00;
TRISB=0X00;
portb=0x00;
Spi_Init_Advanced(SLAVE_SS_ENABLE,DATA_SAMPLE_MIDDLE,CLK_IDLE_LOW,HIGH_2_LOW);
while(1)
{
gdata=Spi_Read(buffer);
if(gdata==3)
{
portb.f0=1;
}
}
}
