Prototyping/ making a dropdown

So I'm trying to make my prototype work. In preview mode, what is happening is i've made a dropdown on my home page (page 1).  I added a link to a different page (page 2) in that dropdown.  I click it, it loads and takes me to (page 2).  Then i made a new dropdown for that page but when i click on that one...it reverts to the original page (page 1) instead of staying on (page 2).  The dropdown is doing what it is suppose to, it just the page below the overlay kepts reverting back to page 1.   Is there a way to make it so that doesn't happen?  Any help would be greatly appreciated!
