Form

hello
I’m trting to make a form with Flash 8. In the tutorial they say :

“Finally, we need a button to actually submit the form. Pull out a Push Button symbol instance from the Components panel, and add it to your almost-complete form. Alter the label via the Properties panel, so that it says something a little more helpful.
While in the Properties section, add a click event handler to the form. This is an ActionScript function that is invoked whenever the button is clicked.”

How to add Click Event Handler? In Flash 8 Properies - Parameters there is no such category as Click Handler?
Thanks
