Interrupt in LPC2148

[Omkar_Trivedi]

hey can anyone please help me ASAP in finding what is wrong with this interrupt program.
Im trying to turn a led on by using External interrupt.
Here is the code:

#include <lpc214x.h>
#include <string.h>
#define CR 0x0D#include <stdio.h> 




void ExtInt_Serve2(void)__irq;

/*----------------------------------<   INT Initialization  >------------------------------*/
void ExtInt_Init2(void)
{PINSEL0  |= 0x80000000;
VICIntSelect = 0x00;	
	EXTMODE  |= 4;										//Edge sensitive mode on EINT2
	EXTPOLAR = 0;										//Falling Edge Sensitive
																			//Enable EINT2 on P0.15
	VICVectCntl1 = 0x20 | 16;							//Use VIC0 for EINT2 ; 16 is index of EINT2
	VICVectAddr1 = (unsigned long) ExtInt_Serve2;					//Set Interrupt Vec Addr in VIC0
	VICIntEnable |= 1<<16;								//Enable EINT2
}

 void DelayMs(unsigned int count) 	
{  
						
									
    unsigned int i,j;		       	
    for(i=0;i<count;i++)
	{
		for(j=0;j<1000;j++);
	}

}

void main()
{
	PINSEL0  |= 0x80000000;	
	IO0DIR = 0X000000ff;
	
	ExtInt_Init2();							//Initialize Interrupt 2
	
	
	
}

void ExtInt_Serve2()__irq
{
	
	IOSET0=0X000000ff;
	
	
	EXTINT |= 4;
	VICVectAddr = 0;
}
