Passing a Variable to a Function Hooked to Genesis Entry Content

[AJD]

I'm working with a custom page template in Genesis and need to remove the post content and replace it when a certain condition is set. That part is working fine, but I also need to display information from a variable in the new content.

It seems simple, but something isn't working, here's my template:

    //* Template Name: Notification Template

    $notice ="ALERT!"; //This will be set dynamically from code above, but I'll keep it simple for now. 

	if($notice){

			//echo $notice ; // If I echo here, it displays at the top of the page.

			remove_action( 'genesis_entry_content', 'genesis_do_post_content' );
			
			add_action ( 'genesis_entry_content', 'do_custom_content', 5 );
			
			function do_custom_content(){							
				
				echo $notice; // This is not displaying anything!
                echo 'Test Output'; //This text does display
				
			}
		}

When I echo the $notice in the do_custom_content() function, nothing is happening. So, it is probably that I don't understand how the php is working, since $notice is not passing through into the do_custom_content() function.

Update: This worked!

if( $notice ) {

    remove_action( 'genesis_entry_content', 'genesis_do_post_content' );

    add_action ( 'genesis_entry_content', function() use ($notice) {
        echo $notice;
    }, 5 );

}
