Finding Array Items help

What are the issues with my code? I can't seem to figure this one out. I've watched the preceding video several times now and don't see where I went wrong.

def find_index(name)
    index = 0
    found = false
    todo_items.each do |x|
      if x.name == name
        found = true
      end
      index += 1
      break if found
    end
    if found
      return index
    else
      return nil
    end
  end

Now my code has disappeared and the code included with the challenge has changed completely (only included the specific method but now when revisiting, the whole class is included) - what is going on?

Hi James,

It looks like you are breaking the loop out after you increment index, so if an item is found, your code will return the index of that item plus one. I got a pass with:

def find_index(name)
    index = 0
    found = false
    todo_items.each do |item|
      if item.name == name
        found = true
        break
      end
      index += 1
    end
    if found == true
      return index
    else
      return nil
    end
  end
