Validate Form doesn't show ?

["PhilAJ" <webforumsuser@xxxxxxxxxxxxxx>]

I have created a page full of ASP fields, in a form, plus a submit button - so 
as to capture data into a database. It all works fine and puts data in there.

 I would now like to do2 things;

 1. Default the currnt date and time into a field that is sent back to the 
database - can't work out how to do that

 2. Validate the form. Reading the Help it says to highlight the Form Tag - 
select behaviours - and pick Validate Form ....BUT - the Validate Form option 
is greyed out !! I've tried selecting the form, the submit button, the Hidden 
Insert value etc ...but cant get at it.

 Any ideas much appreciated
