Caught AttributeError while rendering: 'WSGIRequest' object has no attribute 'get'

Ok more on forms. I have finally got my form to validate, post and redirect to page it needs to. Now my issue is when I return to the page with the form I get this error:

Caught AttributeError while rendering: 'WSGIRequest' object has no attribute 'get'

Seems the only way to restore it to work is to delete the forms.py replacing what was not working before. Add what is working and I can get it to work ONCE. Any ideas what can cause this issue?

FORMS:

class LeadSubmissionForm(forms.ModelForm):
    """
    A simple default form for messaging.
    """
    class Meta:
         model = Lead
        fields = ( 
            'parent_or_student', 'attending_school', 'how_much', 'year_of_study', 'zip_code', 'email_address', 'graduate_year', 'graduate_month', 'email_loan_results'
        )

VIEWS:

@render_to("lender/main_views/home.html")
def home(request):
    if request.method == 'POST':
        form = LeadSubmissionForm(request.POST)
        if form.is_valid():
            form.save()
            return HttpResponseRedirect(reverse("search_results"))
    else:
        form = LeadSubmissionForm(request)

    testimonials = Testimonial.objects.filter(published=True)[:3]
    return {'lead_submission_form':form,
        'testimonials': testimonials,}

MODELS:

    YEARS_OF_STUDY = get_namedtuple_choices('YEARS_OF_STUDY', (
