File downloading problem

Hi,
I am having downloading problem.The files are uploading successfully but when i click on the link to download it gives me the error

Message: file_get_contents(folder/somefile_pdf) [function.file-get-contents]: failed to open stream: No such file or directory.
I don't know why the file name is replaced with "_". Here is my code

Code:

function dpaper($name){
        $name // this name is changed to somefile_ext
        $data=file_get_contents("folder/".$name);
        force_download($name,$data);
        
    }
