Hide Sidebar on a Category

Hi,

I’ve read all about custom templates and conditional tags and I was able to hide the sidebar on specific pages by using a custom page template that I simply removed the get_sidebar.

Now, I am trying to use the conditional tag with the ! to exclude, as follows:

<?php
if ( !is_category(‘how-to-sail-tips-and-tricks’ ) ) {
get_sidebar();
}
?>

The sidebar keeps showing up on my category page.

Any clues?

Thanks,

Kory
