Can someone please tell me why I am getting this error and how to fix it?
numpatients = int(request.vars.name);
<type 'exceptions.TypeError'> int() argument must be a string or a number,
not 'NoneType'
*db.py*
db.define_table('post',
Field('patient'),
Field('attime'),
Field('age')
)

*index.html*
<form enctype="multipart/form-data" action="{{=URL('default',

def postform():
inputs = [];
numpatients = int(request.vars.name);
for i in range(0, numpatients):
inputs.append(db.post.patient.clone(name='%s_%s' %
(db.post.patient.name, i)))
inputs.append(db.post.attime.clone(name='%s_%s' %
(db.post.attime.name, i)))
inputs.append(db.post.age.clone(name='%s_%s' % (db.post.age.name,
i)))
form = SQLFORM.factory(*inputs)
if form.process().accepted:
for i in range(0,numpatients):
db.post.insert(post=form.vars['patient_%s' % i])
db.post.insert(post=form.vars['attime_%s' % i])
db.post.insert(post=form.vars['age_%s' % i])
elif form.errors:
response.flash = 'form has errors'
return dict(form=form)
I want to prompt the user to enter a value of how many patients to enter
for the session, they are redirected to a page where a single form is
displayed and there are multiple form field instances displayed based on
the number of patients they want to enter for that session. When I click
submit after filling the form, I keep getting that error and I don't
understand why or how to change it because I need that value from the
previous page to know how many form field instances to display.
