Three greater then less then statements and not getting correct calculation

[CJ Densmore]

For program to work, you select one of two radio buttons and get a different calculation based on each...

I have tried every form of algebraic greater then, less then, etc. When I run the program and select retailer (bolded and underlined code), any number above 10 calculate to the number that is supposed to be for the numbers 4 to 9. What am I doing wrong? As requested, I wrote the multiplication outside of the select case structure... Thank you!

Public Class Form1

Private Sub exitButton1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles exitButton1.Click

Me.Close()

End Sub

Private Sub submitButton1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles submitButton1.Click

Dim wholesale As String

Dim inputquantity As Integer

Dim outtotal As Integer

Dim retailer As String

Dim numx As Integer

wholesale = wholesaleRadioButton1.Checked

retailer = retailerRadioButton2.Checked

inputquantity = unitsNeededTextBox1.Text



Integer.TryParse(totaloutputLabel2.Text, outtotal)



Select Case True


Case wholesale

If inputquantity <= 4 Then

numx = 10

ElseIf inputquantity >= 5 Then

numx = 9

End If

Case retailer


[B][U]If inputquantity <= 3 Then

numx = 15

ElseIf 4 > inputquantity < 9 Then

numx = 14

ElseIf inputquantity >= 10 Then

numx = 13[/U][/B]

End If

End Select

outtotal = numx * inputquantity

totaloutputLabel2.Text = outtotal

End Sub

End Class

I don't know if this'll help but at line 55 try this"

ElseIf inputquantity > 3 And inputquantity < 10

this'll work for range 4 to 9
