If Then and controls [Resolved]

[teamdad]

I have hit a snag in a program I am trying to create. I came up with this program as a goal for myself in my efforts at learning VB.NET; I would like to finish the darn thing mainly to help myslef learn but also to help my mother's obsession with the lottery. Here's the code I have at the moment that throws all kinds of errors.

Private Sub Button1_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click


        Dim Output = TextBox1.Text              ;Where the results are displayed in multiline
        Dim Rangeone = TextBox2.Text          ;Lowest number to randomize
        Dim Rangetwo = TextBox3.Text          ;Highest number to randomize
        Dim Picks = TextBox4.Text                 ;How many seperate rows of numbers is displayed
        Dim Plays = TextBox5.Text                 ;How many numbers per row are displayed
        Dim r As New System.Random()

        If Picks = "1" Then
            Output.Text = r.Next(Rangeone, Rangetwo + 1)
        Else : Picks = ""
            MsgBox("You must enter the number of picks")
        End If

        If Picks = "2" Then
            Output.Text = r.Next(Rangeone, Rangetwo + 1) & vbCrLf
        Else : Picks = ""
            MsgBox("You must enter the number of picks")
        End If

        If Picks = "3" Then
            Output.Text = r.Next(Rangeone, Rangetwo + 1)
        Else : Picks = ""
            MsgBox("You must enter the number of picks")
        End If
    End Sub

End Class

I need help showing the correct number of rows
as in the commented section of Dim Picks = TextBox4.Text

I need help formatting the code so that it will show the correct number of numbers per row
as in the commented section of Dim Plays = TextBox5.Text

The output of each number in each row needs to be seperated with a [ before each number and a ] after it too.

Example input for Rangeone = 1
Example input for Rangetwo = 12
Example input for Picks = 3
Example input for Plays = 6

Example of output would look like
[02] [10] [03] [06] [05] [09]
[07] [08] [04] [11] [01] [12]
[03] [02] [12] [01] [09] [06]

Pointers, thoughts and examples are appreciated but remember I am very new to VB.NET still.
