Problem with writing to a file

[Mervine, Keith]

Greetings listers,
        Having a small problem writing to a file.

The code below should write the information to a comma delimited file.

void do_dump_weapons_cd( CHAR_DATA *ch, char *argument )
{
    OBJ_INDEX_DATA *pObjIndex;
    FILE *fp;
    int vnum,nMatch = 0;
    char buf[MAX_STRING_LENGTH];
    OBJ_DATA *obj;
    int level;
    int avgdam;

    fclose(fpReserve);

        fp = fopen("../../public_html/files/weap-cd.txt","w");

        fprintf(fp,"Vnum,Name,Level,Number,Dice,Avg,Resets\n");

        for (vnum = 0; nMatch < top_obj_index; vnum++)

        if ((pObjIndex = get_obj_index(vnum)) != NULL)
        {
                nMatch++;
                obj = create_object( pObjIndex, 0 );

                switch ( obj->item_type )
                {
                case ITEM_WEAPON:
                        avgdam = (((obj->value[1]*obj->value[2]) +
obj->value[1]) /2);
                        sprintf( buf, "%d,%s,%d,%d,%d,%d,%d\n",
                                                 obj->pIndexData->vnum,
                                                   obj->name,
                                                   obj->level,
                                                   obj->value[1],
                                                   obj->value[2],
                                                   avgdam,
        
obj->pIndexData->reset_num);
                        fprintf( fp, buf );
                break;
                }

        }
    fclose(fp);
    fpReserve = fopen( NULL_FILE, "r" );
    send_to_char( "Done writing files...\n\r", ch );
}

However when I run the command the mud crashes....If I remove the
obj->name portion of the sprintf, it runs just fine...can someone spot
the problem in this code?

Ive tried obj->pObjIndex->name as well, to no avail.  

Any help is appreciated. TIA
