Using if formula to switch between bookmarks

[Newbie777]

Hello,

I'd like to write a measure to switch between bookmarks to use in a button to toggle between bookmarks.  The bookmark formula for the YTD set expression is like below, and I want to toggle between YTD And full year bookmarks and apply vivid color in the button when YTD bookmark is applied.  But how can I incorporate the bookmark set expression in an if formula?  

{<Month={'Jan','Feb','Mar','Apr','May','Jun','Jul'}>}

Thank you for your help.
