call model function from within model

[eluser]nigelb[/eluser]
i have a model that has several functions to process orders... Is it possible for me within a function in that model call other functions within the same model - if so how do I go about doing that.

answered my own question....

in a function use this to call another function in the same model...

Code:

$this->deliveryPrice($delivery);
