I hid a box on a certain page using Corvid, but when I hit the back button, it remains hidden on the home page.

I used this Corvid tutorial to hide a box on a page. When I go to that page from the home page, the box is hidden. However, when I hit the back button, the box remains hidden on the home page when I only want it hidden on the page I changed the code on. How do I fix this? Thanks!

// On your home page, add the following code
$w.onReady( function() {
$w(“#mybox”).show();
} );

Thank you so much!!
