SPI problem- communication successful only with 1-byte data

SPI String

I have successfully used SPI communications between two microcontrollers. That was when I am sending 1-byte data, but when I used to transfer a string the slave seems to be getting only the first byte, can you tell why is this happening?
here is the master code:

if(slave == TRUE)
{
	 CSpin=0;
	 Delay10TCYx(50);
	 putsSPI(slave_stream);
	 CSpin=1;
	 count++;
	 if(count==10) {
	  slave = FALSE;
	  count=0;
	 }
}

here is the slave code:

if(DataRdySPI()) {
  getsSPI(master_stream, 5);
 
  received_data0 = master_stream[0];
  received_data1 = master_stream[1];
  received_data2 = master_stream[2];
  received_data3 = master_stream[3];

  switch(received_data0)
  {
	case 'A':
	 LED=0;
	 for(i=0;i<8;i++)
  	  Delay10KTCYx(0);
 	 Delay10KTCYx(176);
	 Delay10KTCYx(176);
	break;
	case 'B':
	 servo0=0xFBC6;
	break;
	case 'N':
	 servo0=0xF1FD;
	break;
	default: break;
  }

 if(received_data1 == 'N') {       //<-------------this part doesn't get executed
	for(i=0;i<8;i++)
  	  Delay10KTCYx(0);
 	 Delay10KTCYx(176);
	 Delay10KTCYx(176);
	 servo0=0xF883;
 }

}
