hi Reiner I think what you want to do is controlled in the view not the model.
in your view do something like this:
context = {'form':form, 'infotext': "some informational text"}
return render(request,'form.html', context)
then in your template you can refer to it as follows:
{{
form.name}}
{{ infotext}}
{{form.Ans1_OKH}}
{{form.Ans2_OKH}}
{{form.Ans3_OKH}}
hope that helps ...
