mainpage() problem

[eluser]london77[/eluser]
I am quite new in CI and wanted to make some practices from book. But somehow my code giving me an error.

Fatal error: Call to undefined method Start::mainpage() in C:\wamp\www\packt\application\controllers\start.php on line 18

I have tried to find the mainpage() method but got no info about it in google.

here is the part of code mentions the mainpage()

Code:

if($this->_checkme($username, $password)==TRUE)
{

$this->mainpage();
}

all helps and interests are appreciated.

Thanks in advance.

It appears that you don't have a

Code:

mainpage()

method in your Start controller.
