Bypass HTML Field Restrictions

This time I learn about Bypass HTML Field Restrictions.
I bypass the html form. In order to pass this lesson, I must submit the form with each field containing the value of unallowed. I have to submit an invalid value for all six fields in one delivery form provided. that is : select field which has two choices, radio button which has two choices, input field which retricted to 5 character, and disableinput field with a form that can not be filled.
And this some way that I have tried to bypass it :

First I submibt that form as usual and I did not find any change


Then I tried to intercept request by webscarab, I change values that not provided there. but I not find any changes too.

I studied again after it there are only 5 fields in the request when the procedure mentioned there are 6 fields. then I add a new field that is itself disableinput field, the parameter I get from the source web page. but I not find any changes too, I can not bypass it.


After that I tried different values ​​but can not bypass as well. 

can anyone help me to learn that ?
