Inputs Remember that the form must be named, or you can't refer to it. If you have more than one form in a document, the names must be unique. Each form input that you want to refer to must also be named. To validate a text field, check the value property, which is a string. See page 53 of the Rhino book.
Arrays are a sequence of numbered objects.
See page 72 of the Rhino book. A menu also is an array of values. The browser records the index of the one that was selected. See page 76 of the Rhino book. Add the least amount of code as possible at each step.
