Using Cookie from javascript on hosting

[palvids]

Hi,

In my web page I have written a JavaScript in which one cookie is created which stores a value.
I hv used alert after creating cookie on same page.but,it does not show cookie value & displays some error like-

_utma=241212821.12181130901266200.1240904513.12428 83389.1242883537.26;
..............


I hv redirected one web page to the same domain on button click.
I want to use that cookie value in that page.


It's working on local host.
But not on server(hosting).It displays "Undefined"


Thank u.
