Sure, by using a general form validator. Have a look at the following snippet:
signup = form.Form(
form.Textbox('username'),
form.Password('password'),
form.Password('password_again'),
validators = [form.Validator("Passwords didn't match.", lambda i:
i.password == i.password_again)]
)
As you can see, when you create a form you can pass an additional list
of which that can work on the form as whole (i.e. access all the
registered fields); there shouldn't be too hard to adapt the previous
example to your specific use case.
Please, get back to us if you need further help.
