Option Button Properties Change Based On A Checkbox

I would like to set up some option buttons so that the will be become visible and enabled when a check box is checked, and the opposite when the same checkbox is not check. This is my problem

Private Sub cbpDiscAlum_Click()
Dim myOption As Control
Dim myValue As Boolean
myValue = cbpDiscAlum.Value = True
If myValue = True Then
For Each myOption In pDiscounts.Controls
myOption.Visble = True
myOption.Enabled = True
Next myOption
Else
For Each myOption In pDiscounts.Controls
myOption.Visible = False
myOption.Enabled = False
Next myOption
End If
End Sub

It is the 5th command where it gets hung up: For Each myOption In pDiscounts.Controls. I am sure I am spelling both of the names correctly: the checkbox, and the group name.
