Require A Defined Number of Selections on a Checkbox Field in a Form?

[megweber221]

I am working on a form where one of the fields contains a number of checkboxes. The question instructs survey respondents to "Select your top three." Is there a way to require that people select 3 out of the 12 checkbox options in the field?
