Pop-up Tutorial Question

In this tutorial, the address is going to an url but how would you direct this to a file on your local computer.
Why can’t i just do address = “samples.html”; It should be soo simple but it doesn’t work.

on (release) {
//customize the window that gets opened
// 0 equals NO.
// 1 equals YES.
address = “http://www.kirupa.com/modular/pop-up.htm”;
target_winName = “kirupa”;
width = 400;
height = 300;
toolbar = 0;
location = 0;
directories = 0;
status = 0;
menubar = 0;
scrollbars = 1;
resizable = 0;
//sends data back to the function
openWinCentre(address, target_winName, width, height, toolbar, location, directories, status, menubar, scrollbars, resizable);
}
