I am using the default 'advanced presentation' template to create a presentation. I've gotten the presentation to run perfectly, adjusted the size to my PNG files... but my client wants 4 checkboxes on the last page to be selected before the user can hit a 'next' button. the button redirects them to a URL.

I've tried to search on several different solutions and the most obvious seems to be to 'validate' the 4 fields (called 'complete1, complete2, complete3, complete4) and generate an alert when the button is pushed. I also tried to create listeners and arrays that took note of when all the checkboxes are selected but I've had no luck. I have not come close to 'disabling' the button or generating an alert ... at least I don't think I have. Every time I plug in some code in the script frame or attached to the button it just cycles through the screens effectively breaking what did work.

Here is the script used in the default player:

This is the code used in the movie instance:

PHP Code:
/* Click to Go to Web Page
Clicking on the specified symbol instance loads the URL in a new browser window.

Instructions:
1. Replace http://www.adobe.com with the desired URL address.
   Keep the quotation marks ("").
*/

attest_symbol.addEventListener(MouseEvent.CLICK, fl_ClickToGoToWebPage);

function fl_ClickToGoToWebPage(event:MouseEvent):void
{
    navigateToURL(new URLRequest("http://www.adobe.com"), "_blank");
} 
I'm a Flash scrub so any guidance would be much appreciated. To be specific - I want to require the 4 checkboxes be selected before a user can use the 'Next Page' button.
