setting variables in controller confusion

[eluser]september28[/eluser]
Hi there,

Just wondering if i have 2 functions in a controller say add and add2, could i set a variable in add and then reuse it in add2??

eg.

Code:

function add() {
    $this->myvariable = 'hello';
}

function add2() {
    echo $this->myvariable;
}

In my particular example each function is a different stage of a form and i only want to have to define the id for a record once and then reuse it at various stages of the form (add, add2 and add2)

Thnaks in advance
