[solved] Scaffolding Problem

[eluser]Devyn[/eluser]
Hi, I'm just new and I was following 20 Minutes blog tutorial.
The problem is I got "http://example.com/index.php/blog/scaffolding/add" which is running from "http://localhost:8888/ci/index.php/blog/scaffolding" after I declare

Code:

$route['scaffolding_trigger'] = "scaffolding";

Where can I change "http://example.com" to "http://localhost:8888" since I'm running on Mac with MAMP.

Please help me.
Thanks in advance!
