getting submitted values from dynamically-created form?

[Crawford Tait]

I've been following the example here - https://processwire.com/api/ref/inputfield-form/

Rendering etc is fine but I don't know how to get the submitted values, this:

$name = $form->get('your_name')->attr('value');

doesn't work - the get returns NULL

I can't find out how to get the values apart from just getting them from $input->post

Any ideas?

Thanks!
