I would like to show an alert if no check box was checked in a field.

Microsoft® Office Front Page® 2003 allows you to create some custom validation within the form feature.(For more information on how to create form validation using the Front Page form feature, see About creating forms in Front Page 2003.) However, if the form validation provided in Front Page does not suit your needs or the site on which you are working is hosted on a server that does not have Front Page Server Extensions from Microsoft installed, you may need to create custom form validation.
The purpose of a form validation script is to return a boolean value ('s to reference form fields, but that can lead to namespace conflicts and why make things more complicated than necessary.
where, o Form is a reference to the form object passed to the function using as shown in the form above.As of version 1.92, this is easier to do using the min/max/equals_num_value attributes (to validate sums), or the em_validation_q function, which lets you refer to other variables when you validate the current question Expression Manager.The main problem is that it can't be accessed using ID because every checkbox will have different ID.NET application on the server that provides the functionality that your form needs for processing after a customer has submitted it.Because the code is stored on the server, server-side validation requires a roundtrip to the server.These methods are very convenient to use, but they do not provide the functionality of clearing all the fields, including their default values.
