multi page forms and genral form question

[eluser]The Casual Bot[/eluser]
Got it i did now i could set send a second value to set_value

i have however had made a change to the session lib but unsure if this is the best way to do it
i wanted to use a multidimensional array to store the form data as per page if you get me

iv added to session lib

Code:

function userdataarray($item, $item1)
    {
        return ( ! isset($this->userdata[$item][$item1])) ? FALSE : $this->userdata[$item][$item1];
    }

is this the nest way or do you know a better one
