Making changes to the User Registration Forms

I have spend the last couple of hours trying to add new fields to the users_Registration Form using the CSS Form Builder.

The Form opens ok in CSS Form Builder I can see the original fields. However, once I add the new fields (Birth Month, Newsletter Format, Captcha), edit the design and then click finish, all of the formatting from the original form disappears.

I am left with a basic Form and the worse part is when I upload the document it does not work.

Yes, created and bond the new fields to the database.

When I upload the updated form (using the same name "users_Registration.php"). It does not work.

Is this normal? If it is, then what "exactly" do I have to do to keep the original formatting of the user_Registration document?

I also tried just adding the fields to the form and binding them without using CSS Form Builder and got the same results.

In both cases the form will not open in my browser once I upload it.

I know I have to update to "Profile" and "Search" documents in the Solution Pack but if I can not get the user_Registration document to update

I have updated my database with the two new fields and my "MySQL" Database is up and running.

I am beginning to think the forms in the User Registration Package can not be updated or changed and I have to create my own
registration from. Is this the case?
