Array of Undefined size - Declaration in Structure causes pass over/hang?

[IndeX_11]

Hello again!

I'm having a problem whilst attempting to create a small database of sorts.
When trying:

Public Class Form1
Structure Items
        Dim Food As String
        Dim Extras() As String
        Dim Price As Double
    End Structure
    Dim Food(6) As Items

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        Food(0).Food = "Burger"
        Food(1).Food = "Chkn Burger"
        Food(2).Food = "Sausage"
        Food(3).Food = "Nuggets!!!!"
        Food(4).Food = "CornDog"
        Food(5).Food = "Fries"
        Food(6).Food = "Onion Rings"
        ' ''Burger
        Label1.Text = "One"
        Food(0).Extras(0) = "Cheese"
        Food(0).Extras(1) = "Bacon"
        Food(0).Extras(2) = "Extra Onions"
        ''Chkn Burg.
        Label1.Text = "Two"
        Food(1).Extras(0) = "Cheese"
        Food(1).Extras(1) = "Xtra Sauce"
        '' Sausage
        Food(2).Extras(0) = "Cheese"
        Food(2).Extras(1) = "Chilli"
        'Nuggets
        Food(3).Extras(0) = "Plum"
        Food(3).Extras(1) = "Sweet & Sour"

        Food(0).Price = 1.25
        Food(1).Price = 1.75
        Food(2).Price = 2.0
        Food(3).Price = 2.0
        For X = 0 To Food.Length
            cbItemChoose.Items.Add(Food(X).Food)
        Next
    End Sub

It runs the program without error, but the "cbItemChoose" Dropdown does't get populated. I put the lines to change the "Label1" as a test, at which it gets to "One" but never "two".
If I comment out every line that has the Food(x).Extras(y) in it, the program populates the dropdown, but runs into an error as expected when trying to use the extras.
I'm not sure if there's another way to declare this, or if it's just another error on my fault of HOW I'm declaring this.

You'll notice, should you choose to look at the attachment, that I have a lot of variables at the top. The point of this structure is to make rid of all this messy declaration, as I am striving for efficiency.

Thanks in advance for any help/tips.
