pagination didn't work

[eluser]marjune[/eluser]
well my problem is the pagination, since the total rows is 9 then the per page is 5 the pagination look like this
{

display 5 records here

}
1 2 >

when i click the 2nd page which the four remaining records will display the URL look like this http://mysite.com/ci/index.php/furoms/&per_page=5

then it will display 404 Page Not Found

The page you requested was not found.
