Problem with archives

Hello everyone! I have a problem with archives…
I have one page named News, where appear 4 last posts.
On that page i have right sidebar, where (NOW) archive dropdown list;
When i click to one of list items there is no entries displayed on page.
I created archive.php, and after that, list item showed categories list and when i click on one item of this list there is no entries… But it should be like that:
Ex: I click on Februar item from the list, and it should display only Februar posts. It is not standart template so i havent idea how to fix it.
