How do I make mandatory answers in form fields before submission?

[Admiral Jack]

Hello: I am receiving a new form of spam by spammers using my guest book form
and sellecting only the state and adding their liks in my comments area. How
may I make mandatory the guest having to answer each question before
submission?
Thank you

Use validation to make every field a required field.
Open the web in FrontPage, then the guestbook form page.
Right click each field in turn, and choose field properties.
Tick Validate button, then required box.
Click OK, OK

Repeat this for each field.

Before you save and close the page, change something: example delete a
word and add it back. This "dirties" the page and ensures the changes
in field properties are properly saved when you save the page.

If the spammers have JavaScript disabled this will do nothing. In this
case you will need server-side scripting (asp, php, asp.net, Perl/cgi
etc) and possibly a database for the guestbook.
