I ask for help opening a link submenu in iframe

Anyone with the patience can help me to create an iframe and load it into the external pages retrieved from the navigation menu

In the navigation menu I have linked a new page and the address is:
http://www.mysite.com/page/name-page

where now I put a block with Deanos Tools structured as follows:

echo '<iframe src="http://www.externalsite.com" width="100%" height="1100" frameborder="0" scrolling="no"> </ iframe> ';

I would like to have a submenu that contains 5 items

external page 1 ---> http://www.mysite.com/page/name-page?iframe=lobby
and $lobby = "http://www.externalsite.com/lobby.php"

external page 2 ---> http://www.mysite.com/page/name-page?iframe=ranks
and $ranks = "http://www.externalsite.com/ranks.php"

external page 3 ---> http://www.mysite.com/page/name-page?iframe=faq
and $faq = "http://www.externalsite.com/faq.php"

external page 4 ---> http://www.mysite.com/page/name-page?iframe=rules
and $rules = "http://www.externalsite.com/rules.php"

external page 5 ---> http://www.mysite.com/page/name-page?iframe=exit
and $exit = "http://www.externalsite.com/exit.php"

how do I define iframe to open these pages?

Any help here?

What should I do, I have to open a job in http://www.boonex.com/unity/jobs/home/ ?

the alternative that I found I don't like... I don't want to create 5 new pages and 5 new Deano's blocks

thanks!
