The following example uses the GroupName property to create two groups of OptionButton controls on the same form.
To use this example, copy this sample code to the Script Editor of a form. To run the code you need to open the form so the Open event will activate. Make sure that the form contains five OptionButton controls named OptionButton1 through OptionButton5.
Sub Item_Open()
set OptionButton1 = Item.GetInspector.ModifiedFormPages("P.2").Controls("OptionButton1")
set OptionButton2 = Item.GetInspector.ModifiedFormPages("P.2").Controls("OptionButton2")
set OptionButton3 = Item.GetInspector.ModifiedFormPages("P.2").Controls("OptionButton3")
set OptionButton4 = Item.GetInspector.ModifiedFormPages("P.2").Controls("OptionButton4")
set OptionButton5 = Item.GetInspector.ModifiedFormPages("P.2").Controls("OptionButton5")
OptionButton1.Caption = "Widgets"
OptionButton2.Caption = "Widgets"
OptionButton3.Caption = "Widgets"
OptionButton1.GroupName = "Widgets"
OptionButton2.GroupName = "Widgets"
OptionButton3.GroupName = "Widgets"
OptionButton4.Caption = "Gadgets-Group2"
OptionButton5.Caption = "Gadgets-Group2"
OptionButton4.GroupName = "Gadgets-Group2"
OptionButton5.GroupName = "Gadgets-Group2"
End Sub
