sessions not enabled on go daddy server

[eluser]labao[/eluser]
Hello, I am using codeigniter to build a car rental website and I am having trouble implementing it on a godaddy server. I am still in school so forgive me for not being so technical but the sessions that I am putting variables into don't seem to want to be recorded.
I am using the following come to dump the var into session data:

Code:

$vehicle=$this->input->post('vehicle');

then

Code:

$this ->session->set_userdata('vehicle', $vehicle);

and then I am pulling the vars out on the last page via this line of code:

Code:

$car=$this->session->userdata('vehicle');
   echo $car;

Also this code works locally... but not remotely. I can go to the website and go through all the steps and have it run perfectly on my machine but when I go try it on another computer, the sessions aren't created and the application doesn't work.

Any help is appreciated. This is a school project and time is of the essence!

Thanks,

Lorne.
