Hello everyone,
I have created below page but i am having difficulty to run it through as the pages links that i have created seems dont work.
I am using dreamweaver 8 .
when i click on the post links on my admin page, the links send me to the editpost page however when i click on the previous or next link to see the other posts nothing happens.

can anyone help me how to avoid this happening.

Thanks in advance
