assembler

another question on assembly.
i'm having problems with inline assembly.

assignment.cpp(27) : error C2443: operand size conflict
assignment.cpp(28) : error C2443: operand size conflict
assignment.cpp(29) : error C2443: operand size conflict

my code is the following

#include<iostream>
using namespace std;
 
int sum(int a,int b);
 
int main()
{
	int a=0,b=0,num=0;
 
	cout<<"enter integer";
	cin>>a;
	cout<<"enter integer";
	cin>>b;
	num = sum(a,b);
	cout << num;
 
	return 1;
}
 
int sum(int a, int b)
{
	int n=0;
 
//it doesn't like my inline block here
//i'm assuming it means that the integers a, b, n differ in size from the ah register. 
//how would i fix this? cast?
	_asm
   {
			mov ah, a 
			add ah, b
			mov n, ah
   }
 
	return n;
}

So, I figured it out. I used short instead of int, and it worked.
