Assembly Definition Errors

Question

I am trying to mess around with my assembly function to get it to work but have ran into a couple of errors that are difficult to get by. One is A2005 which states symbol redefinition :_Average. The other one is A1010 which states unmatched block nesting :_Average Any help is appreciated.

.cpp code

#include<iostream>

using namespace std; 

extern "C" long Average(long, long[]);

int main()

{ 
long Array1[10] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 }; 
long Array2[11] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 }; 
cout << "Average of Array1 is " << Average(10, Array1) << endl;
cout << "Average of Array2 is " << Average(11, Array2) << endl; 
}

long Average(long, long[])
{
    return 0;
}

.asm file

.386
.model flat

public _Average

.data

.code


_Average    proc
            push    ebp;
            mov     edx, 10;
            mov     ebx, [ebp+12]
            xor     ecx, ecx;

            jnz     Loop1;
        Done1:

            idiv            ebx;
