Getting to The next page in post section?

Hello,

For some reason when I go to the my post section on the frontend of my site, it wont let me view the old articles that I posted. For example, at the bottom of the post section it has "Previous Entries" and "Next Entries" but you cant click these functions. Its at the bottom of the page but its not clickable. This function is a MUST for my site to have, as I want my user to have the ability to view old articles that we have created. Is there a reason for why I cant view the next page of post I did?
