Integrating Salesforce Self Service Portal

I hope I am posting this in the right place - am very new to Drupal and am certain that I am just missing something easy. Have a simple Drupal site. I need to have a page (which I have created) that contains the login form (and after log in the content generated by SalesForce) for the SalesForce Self Service Portal.

SalesForce provides code, but when I place this code (for the login) on a Drupal page - the resulting page looks right, but when you log in, nothing happens.

I am assuming that this is a similar problem to those I've experience with Joomla - and in Joomla you simply use the "wrapper" - is there something similar available in Drupal?

Any help would be greatly appreciated.
