Calling Multiple Models in one Controller

[eluser]amalik[/eluser]
Hi All,

I am creating a website where I need to output data from multiple models into a controller. Its a little forum application. For example on the user page I want to display all of the user data and the messages he got from other members and his posts and much more. This all is in different models. At the moment when I load more then one model into my controller it gives me errors. Can any one help me please. I want to know how can I load multiple models into one controller so I can extract data from them.

I am new to codeigniter. If I am asking a stupid question please forgive me.

Thanks in advance.
A Malik
