Django - Post data not in form.cleaned_data leading to key error

I have a dynamically created form build with Django. When this form is submitted i can see all the data in request.post, that being said when i access form.cleaned_data one of the inputs is not there. This is causing a KeyError when i try to access it.

There are no errors caused by the form and the form is appearing valid. If anyone has any other avenues i could look, i would be very appreciative.

Here is the error:

Internal Server Error: /gluiq/StrategicBrief/

[09/Apr/2019 12:25:51] "POST /gluiq/StrategicBrief/ HTTP/1.1" 500 97452

Here is the View although i don't feel it will help:

def post(self, request):
    if request.method == 'POST':
        files = Files.objects.get(FileName="Strategic Brief")
        self.request.session['activeFile'] = files.id
        form = OutlineBusinessCaseForm(request.POST, request.FILES, Questions=files.questions.all())
        activeproject = request.session['activeProject']

        print(form.errors)
        if form.is_valid():

            current_user = self.request.user
            projects = userProject.objects.filter(id=activeproject, UserID=current_user)
            file = Files.objects.get(FileName="Strategic Brief")
            questions = file.questions.all()
            awnseredQuestion = QuestionAwner(UserID=self.request.user, ProjectID=projects[0].ProjectID, FileID=file)

            a = 0
            while a < len(questions):
                awnseredQuestion = QuestionAwner(UserID=self.request.user, ProjectID=projects[0].ProjectID,
                                                 FileID=file)
                awnser = '{"Title": "' + questions[a].Question['Title'] + '",' + '"AwnserTitle": "' + \
                         questions[a].Question['AwnserTitle'] + '",'



                if questions[a].Question['DropdownList'] == True:
                    ThisQuestion = questions[a].Question['DropdownList_Question']
                    ThisAwnser = str(form.cleaned_data[str('DropdownList_' + str(a))])

Here is the form:

class StrategicBriefForm(forms.Form):

    def __init__(self, *args, **kwargs):

        questions = kwargs.pop("Questions", None)
        super(StrategicBriefForm, self).__init__(*args, **kwargs)
        if questions:
            i = 0
            while i < len(questions):
                question = questions[i].Question

                if question['DropdownList'] == True:
                    self.fields['DropdownList_%s' % i] = forms.CharField(label=question['DropdownList_Question']['context'],
                                                                  required=False)

                i = i + 1

Ended up, as i was re-using code i forgot the change the name of the form i was calling. I should have been calling the StrategicBriefForm in the view instead of the OutlineBusinessCaseForm.

Thanks everyone who tried to help.
