Hi WillThe visible state of elements in dynamic forms is not guaranteed
to be saved, you should set this up as part of the form
initialisation.Each element that has dynamic visibility must have some
data element that is saved for it, in your case, the Radio Button.Use
the Initialise or Form Ready event, to make sure the data is loaded, and
if is it "Other", then display the Course subform.P.S. Some people
prefer to add/remove instances of subforms, rather than use
show/hide.Hope this helps.
