Like I stated in a previous post, its more coder-oriented and without much documentation.
The idea is to first develop your variables list
(Note:You only have to use the vbulletin cleaner on a variable which will allow user input.)
So if my first question was:
$question1="What is your name?";
$explain1="Please enter your name here";
Neither of those have to be passed through vb input cleaner.
-only the $answer1 since it takes user input.
I clean everything... even radio boxes that you think would only be a Yes or No,
just in case a hacker tries to manipulate any input variables.

You cannot use the same variable twice or it is overwritten resulting in possible errors.
So you cannot do:
$question1="What is your name?";
$question1="How old are you?";
This is basic variable handling as you are redeclaring the var resulting in it being overwritten.
If you are trying to use the default form as reference as you make a custom form,
the script is being executed ,corrupting default variables if you are not assigning your own.
So I recommend disabling the default form if you make custom.

After all your variables are assigned properly within the plugin, you then edit the form template
to your liking which takes basic vbulletin template handling.

And also do the same with the output template (answer template) which will be the
template that posts to your thread or post.
Both templates have to use the same variables as you stated in the form plugin.

The easiest way I have found is to write down my questions and answers on paper
or in editor so that I have a basic set.
Then, I go through and create the variables, place them in the order I want in the templates,
and everything should work.

It takes a bit of a learning curve but well worth it.
Maybe someday, the Form Hack will be enhanced to set up the form from adminCP area.
