What is wrong with my if statement?

[JoePage]

I feel kind of silly asking about an if statement but I am having an issue.

I created a goto line form in my application and it works, I am just trying to set some perimeters so it prompts a messagebox stating that the line number they entered doesn't exist. Basically if the number is lower than 1 or higher then the line count. Here is the code, when I have if statements nested like that the error will only work for whichever is first(this case it is the less than 1). I need it to work for both.

Dim page As RadPageViewPage = AutoGamerMain.RadPageView1.SelectedPage
        For Each txt As FastColoredTextBox In page.Controls.OfType(Of FastColoredTextBox)()
            If LineNumberTxt.Text <= txt.LinesCount Then
                If LineNumberTxt.Text >= 1 Then
                    txt.Focus()
                    txt.Selection.Start = New Place(0, LineNumberTxt.Text - 1)
                    txt.DoSelectionVisible()
                    txt.Invalidate()
                Else
                    MessageBox.Show("You have entered a line which does not exist. Perimeters are (1-" & txt.LinesCount & "). Please choose a new line.")
                End If
            End If
            Next

if the number is lower than 1 or higher then the line count

Seriously?

Seriously?

Worded wrong. I'll change it around. It should work like this though? It needs to be both less than the lins count an higher or equal to 1.

Blame it on a long day.

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim page As RadPageViewPage = AutoGamerMain.RadPageView1.SelectedPage
        For Each txt As FastColoredTextBox In page.Controls.OfType(Of FastColoredTextBox)()
            If LineNumberTxt.Text >= txt.LinesCount Or LineNumberTxt.Text <= 1 Then
                MessageBox.Show("You have entered a line which does not exist. Perimeters are (1-" & txt.LinesCount & "). Please choose a new line.")
            Else
                txt.Focus()
                txt.Selection.Start = New Place(0, LineNumberTxt.Text - 1)
                txt.DoSelectionVisible()
                txt.Invalidate()
            End If
        Next
       End Sub

If ln >= 1 AndAlso ln <= count 'the other way round
