Jquery form validation for radio button

Jquery form validation for radio button

Hi,
I am confident that  I am in the right  forum for my question to be resolved. Thanks in advance.

I have a form in which there are five input fields with radio buttons ("YES" and "NO" options). To submit the form the user has to select all the five radio button, with "YES" or "NO" options, If the user does not select any of the options and continues to click on continue button, it should throw an error message. like wise If the user selects two of the options and does not select rest of them and click on continue then also it should throw an error. Please help me withe the Js code for the validation.
