The button can't be removed till after the page is generated again so to keep a person from hitting the button more than once while the page is trying to post causes the same information to be sent twice. Using the javascript to check before sending keeps this from happening. []/forum/images/icons/smile.gif[/]
You could remove the alert box and just return the false statement. Nothing more will happen and the information will still only be submitted once. I just figured it would give the impatient people more incentive to wait... lol []/forum/images/icons/wink.gif[/]
