I'm having a problem with my else statement.. It doesn't seem to be executed.. What I want is if I click on the button "dissapear" all Paragraphs with "Boe" dissapears, but if i click on it again, it appears back. But my else statement doesnt seem to work, the same with the "change" button, if i click on "change", my text formats itself, but if i click on it once more, it goes back to normal. Any help? Thank you!
