i would like to create this-
(xi) any entity or a nominee or omnibus account (including, but not limited to, a corporation, partnership, limited liability company, trust or other entity) in which any person or persons listed in (i)-(x) above has a beneficial interest;
If Investor checks box xi, Investor also must check one of the following:
the entity or account limits participation by beneficial owners that are Restricted Persons to not more than 10% of the profits and losses of New Issues;
the entity or account does not limit participation by beneficial owners that are Restricted Persons to 10% or less of the profits and losses of New Issues; or
the entity or account does not permit Restricted Persons to participate in New Issues to any extent.
i would also like to know if you can do superscript within questions for footnotes?
Yes you can set up a Custom Group question type (advanced section) and set up the first question as the first part of the custom group. The add the second question as the second one and use the hide/show logic for that question to show it if the first question is clicked Yes.
The second question will require a question text but this can be hidden via the css display:none;
see this page: http://help.surveygizmo.com/help/article/link/css-class-names
Also yes you can use <sup>and </sup>
