Index out of range question

try printing the length of all arrays you are using in this block

for (int index4 = 0; index4 < letters.Length; index4++)
                            {
                                if (letters[index4] == hits[index3][0].ToString())
                                {
                                    hitsX = index4;
                                }
                            }

                            if (hits[index3].Length == 3)
                            {
                                hitsY = (int.Parse(hits[index3][1].ToString() + hits[index3][2].ToString())) - 1;
                            }
                            else
                            {
                                hitsY = (int.Parse(hits[index3][1].ToString())) - 1;
                            }
