After reading "Form Submission" at http://www.w3.org/TR/REC-html40/interact/forms.html#h-17.13 this behaviour seems correct.
=== cut here === 17.13.3 Processing form data When the user submits a form (e.g., by activating a submit button), the user agent processes it as follows. Step one: Identify the successful controls ... A successful control is "valid" for submission. Every successful control has its control name paired with its current value. ... If a form contains more than one submit button, only the activated submit button is successful. === cut here === So, you button was not "activated", thus it was not submitted. Noting mostly to myself: regular button which is not a "submit" type, will be sent to the server. So, if I have five regular buttons, all of them will be sent. But at most one "submit" button will be sent if it is "activated", or no submit buttons at all. On 4/29/05, Eoin Dunne <[EMAIL PROTECTED]> wrote: > Rick you hit the nail on the head.
