John,

Looks like Larry stepped out...so I'll jump in.

Call the method anything you want...let's call it convertToWords for this example.

How you call it depends on how you want the form to work. For example, you could call it from the lostfocus() of your numeric textbox (where the user is entering the dollar amount).

* lostfocus() method of textbox
thisform.convertToWords(this.value)
