the code works great! just what I was looking for. I'm don't know anything about this, but I'm starting to run a small site for my studio and I would like to ask how can this code be improved in a way that if I'm on a specific page when I click the button I go to other language versions of that page, right now both buttons take me to one specific page in the specific language.
Like I'm at Work page if I click on the ES button it takes me to Trabajo, but if I'm at the About page and I click on the ES button it takes me to the Trabajo page again, I want to go to the Spanish version page of About. What code needs to be added to make that happen?
