Hello. Could you please help me with some javascript. In a section of my form, I want two radio buttons. When neither button is checked, an alert box will appear. If the first button is checked the form will pass. If the second button is checked, a series of mandatory text boxes are highlighted and must be validated before the form will pass.
Good luck and thanks

The set and unset functions will let you manipulate your radio button functions dynamically:

And here's an example that illustrates how to show/hide a hidden form field when another is clicked:
