I have an array of 3 option buttons Option1(0), Option(1) and Option(2) and a textbox txtNum

Depending on which option button is chosen and what number is input into text box, I want to write a select case: (But I can't see where I'm going wrong! Any hints or tips folks?
Code:
Private Sub cmdSubmit_Click()

Dim Wholesale as String
Dim price As String
Dim Total As Integer

Select Case Wholesale ' Wholesale is the Caption of Option1(0)
Case "1"

    If txtNumRequired <= 5 Then
    price = 50
    Total = txtNumRequired * price
    End If
    
Case "2"

    If txtNumRequired >= 6 And txtNumRequired <= 10 Then
    price = 45
    Total = txtNumRequired * price

End Select

     lblDisplayType.Caption = Option1(0).Tag
     lblDisplay.Caption = "You ordered " + txtNumRequired + " Items" '+ "The cost will be " + Total
     lblDisplayPrice.Caption = Total

End Sub
