sorting an array of structs

Hi all,
Given a csv file and I need to read the data and create a sorted array of structs, each of which contains the country code, name, population and life expectancy. So i've to build an index array in memory and sort it using insertion sort and then write (country code with its offset) to a directory file where I'm able to search using the country code.
here is what I have right now, but the sorted array is not working???

#include	<stdio.h>
#include 	<string.h>
#include 	<stdlib.h>
#include 	"ourhdr.h"

typedef struct				// Country Data struct declaration
    	{  	
		char code[4]; 		// Country Code 
       		char name[50];		// Country Name
		float life_expectancy;	// Life Expentancy of the Country's citizen
		int pop;		// Country's Population
    	} DATATYPE;

typedef struct				// Index Data struct declaration
	{
		char code[4];		
		long int offset;	// offset of the data
	} INDEX;

INDEX StructArray[300];	// for a lot of them
DATATYPE ActualStruct; // for a single struct

void sort(INDEX SortArray[], int n)
{
	int j;
	for(j=0; j < n;j++)
	{
		int k;
		char *temp = SortArray[j].code;
		for (k= j-1; k >= 0; k--)
		{
			if(strcmp(SortArray[k].code, temp) >= 0)
				break;
			strcpy(SortArray[k+1].code, SortArray[k].code);
		}
		strcpy( SortArray[k+1].code,  temp); // strcpy	
	}
}

int main() 
{ 
	int i = 0;
	int size = 0;
	FILE *FI, *FO, *FO2;
	char Line[1000];  // NO input line (delimited by \n) is longer than 1000

	char * Tok;         // token from line
	if((FI = fopen("AC1.txt", "r")) == NULL) // open a stream from "countries"
    		err_sys("Open Fail\n");

	if((FO = fopen("DATABASE.txt", "wb")) == NULL) // open a stream from "countries"
    		err_sys("Open DATABASE Fail\n");

	if((FO2 = fopen("DIRECTORY.txt", "w+")) == NULL) // open a stream from "countries"
    		err_sys("Open DIRECTORY Fail\n");

    while ( fgets( (char *) Line,1000,FI) != NULL) // fill buffer up to newline or eof or error
    {

	Tok = strtok( Line ,",\n"); 	// skip ID number

        Tok = strtok( NULL ,",\n"); 	// this should get the country code 
        ActualStruct.code[0] = Tok[0];
        ActualStruct.code[1] = Tok[1];
        ActualStruct.code[2] = Tok[2];
        ActualStruct.code[3] = 0; 	// To create "string" 

	Tok = strtok( NULL ,",\n"); 	// this should get the country name 
        strncpy(&ActualStruct.name[0],Tok,50);	// copy string at most 50 chars

	Tok = strtok( NULL ,",\n"); 	// skip
	Tok = strtok( NULL ,",\n"); 	// skip 
	Tok = strtok( NULL ,",\n"); 	// skip
	Tok = strtok( NULL ,",\n"); 	// skip 

	Tok = strtok( NULL ,",\n"); 	// this should get the population
	ActualStruct.pop = atoi(Tok);	// convert string to integer

        Tok = strtok( NULL ,",\n"); 	// this one should get life expectancy
        ActualStruct.life_expectancy = atof(Tok);	// convert string to a floating point number

	strcpy(StructArray[i].code, ActualStruct.code);                  // get the current code 
	StructArray[i].offset = ftell(FO);                               // get the current offset in the DATABASE file 

	if (fwrite(&ActualStruct, sizeof(DATATYPE),1,FO) != 1)  // write the struct to the DATABASE file 
		err_sys("fwrite error");

	printf("%5s%50s%15u%18f%10u\n",&ActualStruct.code[0],&ActualStruct.name[0],ActualStruct.pop,ActualStruct.life_expectancy,StructArray[i].offset);

	i++;
	size = i;
	}
	
	printf("Before Sort:\n");
	for (i=0; i<size; i++)
	{
		printf("%s \t %u\n",StructArray[i].code, StructArray[i].offset);
	}	
	
	sort(StructArray,sizeof(StructArray)/sizeof(*StructArray));	// call sort function
	
	printf("After Sort:\n");
	for (i=0; i<size; i++)
	{	
		printf("%s \t %u\n",StructArray[i].code, StructArray[i].offset);
	}

	if (fclose(FI))				// close file descriptor FI
		err_sys("Close error\n");	
	if (fclose(FO))				// close file descriptor FO
		err_sys("Close error\n");	
	if (fclose(FO2))			// close file descriptor FO2
		err_sys("Close error\n");

    	printf("------THE END------ \n");  // and this if not error :)

Before Sort:
DZA      0
AGO      64
BEN      128
BWA      192
IOT      256
BFA      320
BDI      384
After Sort:
DZA      0
AGO      64
AGO      128
AGO      192
AGO      256
AGO      320
AGO      384
------THE END------

what i want is something like that:
After Sort:
AGO    64
BD1     384
BFA     320
...and so on

any help will be greatly apreciated:)
