[sokoban_1]

Would you please tell me the way to correct this kind of error ??
I have thought many many days and I simply cannot solve this . . . .
Unhandled Exception , access violation reading error
Code:

void win(Map*initialMap , Map* currentMap , int x , int y){
	int i;
	int j;
	for(i=0; i < currentMap->height ; i++){				
	// all boxes are pushed into all targets
		for(j=0; j < currentMap->width ; j++){
	if (currentMap->map2D[y+j][x+i]=='@' && initialMap->map2D[y-j][x-i]=='!' )  <-- error
		return ;
		}
	}       
}

int try(Map *initialMap, Map *currentMap, int x, int y, int max_no_of_move, Stack *s) {
	int i,j,k;
	int result=0;
	char q='\0';
	char e[4]={NORTH,SOUTH,EAST,WEST};
	Map tempmap;
	if(max_no_of_move ==0 ) return 0;   
	 win(&initialMap,&currentMap,&x,&y) return 1; 
	  // if not , try each possible directions
	for(i=0;i<4;i++){
			if ( move_keeper(&initialMap,&currentMap,&x,&y,e[i])) {
				 clone_map(&tempmap,&currentMap);
				result  = try  ( &currentMap, &tempmap , x, y , max_no_of_move -1 , &s );
					if(result) { return result;
						//A solution is found
				 		push(&s,e);
				    	}
						else {
							q=pop(&s);
			for(j=0;j<currentMap->width ; j++) {
			for(k=0;k<currentMap->height;k++){
							tempmap.map2D[k][j]=currentMap->map2D[k][j];
			}}
						}		
						return  result;
			}
			}
