For loop not outputting properly when using arrays

Question

I would expect this code when run to output the first line of the array, pause, then output the second line in the array, each line being output with a delay between each character but for some reason it isn't working for me.

        Dim IntroText(4) As String
    IntroText(0) = "Konrad Czajkowski..."
    IntroText(1) = "...Presents"
    IntroText(2) = "...A text based game..."
    IntroText(3) = "...The Legend of Konrad and The Quest for Skairum"

    Dim IntroTextLength As Integer = Nothing
    IntroTextLength = IntroText(IntroText.Length - 1)

    For IntroCounter1 = 0 To IntroTextLength
        For IntroCounter2 = 0 To IntroText(IntroCounter1).Length - 1
            Console.Write(IntroText(IntroTextLength)(IntroCounter2))
            Threading.Thread.Sleep(50)
        Next
        Threading.Thread.Sleep(5000)
        Console.Clear()
    Next
    Console.Clear()

P.s I'm using a console application in VB.NET

Try this.

Dim IntroText(4) As String
IntroText(0) = "Konrad Czajkowski..."
IntroText(1) = "...Presents"
IntroText(2) = "...A text based game..."
IntroText(3) = "...The Legend of Konrad and The Quest for Skairum"

Dim IntroTextLength As Integer = Nothing
IntroTextLength = IntroText.Length - 1

For IntroCounter1 = 0 To IntroTextLength - 1
    For IntroCounter2 = 0 To IntroText(IntroCounter1).Length - 1
        Console.Write(IntroText(IntroCounter1)(IntroCounter2))
        'Console.Write(IntroTextLength)
        Threading.Thread.Sleep(50)
    Next
    Threading.Thread.Sleep(500)
    Console.Clear()
Next
Console.Clear()

It worked! Thank you, couldn't fix it myself, practicing vb for later in life, I'm in college and this is very valuable feedback. Thanks!

It's good that this fixed the OPs problem but it would be worth explaining why.

Code only answers are discouraged. You should at least try to explain why the OP code was incorrect and what your code does to fix the problem.
