  the 
  radiobuttons:
   
Dim hCtrl As Control

   For Each hctrl In Vbox1.children
   If hctrl Is hbox Then

  tb.Clear()
   Else If hctrl Is RadioButton Then
  rb = hctrl 
  rb.value = False   
   Else If hctrl Is checkbox Then
cb = hctrl
   cb.value = False  
  End If
 Next  
   End If
Next
  
  If I directly address the radiobutton in the group by name, it still dosn't 
  clear.
  
  any help appreciated.

 Salut Richard,

 The Apple Human Interface Guidelines specify that one item of a radio
 button group must always be selected.

You can add a forth radio button in the group and set it hidden.
By setting this 4'th to true the others go false.
More correct is to set the 4'th not hidden but label it as 'None of the others'

Not only the 'Apple Human Interface Guidelines' but many other say the same.
Only on web pages the _browser_ (specific IE) does allow none is true.
In fact it is the fault of the web page developer to not set one to true.


Best regards,

 Some time ago we talked about it. If you wanna clear all radiobuttons
 there's an easy workaround. Add a radiobutton (say HiddenRadioButton)  in
 the group and set its Visible property FALSE.

 So when you want to clear radiobuttons, just select the hidden radiobutton,
 HiddenRadioButton.Value = TRUE and all others in the group will be cleared.

 Ciao,

 Stefano
