[avr-chat] URGENT! where is the error in this simple code?

[pulkitmidha]

//please see main() i have desccribed the error there
//please look into it it is URGENT
#include <avr/io.h> 
unsigned char byte0,byte1,byte2,byte3,byte4,d,addr='P',flag=0; 
void uart_init(void) 
{ 

UCSRB = (1<<RXEN)|(1<<TXEN); 
UCSRC = ((1<<URSEL) | (3<<UCSZ0));// 8-data, 1 stop-bit, no parity 
UBRRH=0; 
//UBRRL=25; 
UBRRL=12;//(u08)UART_BAUD_SELECT; 
} 
void USART_Transmitt( unsigned char data ) 
{ 
/* Wait for empty transmit buffer */ 
while ( !( UCSRA & (1<<UDRE)) ) 
; 
/* Put data into buffer, sends the data */ 
UDR = data; 
} 

unsigned char USART_Receive( void )
{
/* Wait for data to be received */
while ( !(UCSRA & (1<<RXC)) )
;
/* Get and return received data from buffer */

return UDR;
}


void main(void)
{
uart_init();
while(1)
byte0 = USART_Receive();//here is where the problem is..byte0 is not getting
the 
//value that i am entering in the hyperterminal..simulated the code on avr
studio..in 
//watch window,byte0 is not getting the value
}
