Sessions (without cookies) and Class Definition problem

[perrio]

HELLO,
I have an include file that defines a class in my main script;

when i call a an object method (a function) that returns a string in the main script I get the error:

Call to a member function on a non-object in /home/xxx/www/myapplication/main_panel.php on line 15

I'm sure that the class is defined properly and that i have used the include directive as the first line of code. It also seems as though that other registered session variables are not becoming available either. (i have confirmed the sess id is being passed in)

What is a member function?

Thanks...

Show me some code please.

$myObj = new SomeObject;
$myObj->dothis();

if function dothis() did not exist in myobj , this error would come back.
