Variable variables & string index arrays

[Anon]

In a hyperlink, the variable $Make is passed with the value of "whoopie":
http://www.blahblah.com?Make=whoopie

In the target page that recieves this variable are a series of string indexed arrays, one of which is an array named "whoopie":
$whoopie = array ("first" => "whips", "second" => "chains") ;

How do I access $whoopie[chains] using the $Make variable's value to pick the array named "whoopie"?

I tried $$Make[chains], but i'm pretty sure PHP is looking for the 'chains' element in $Make, not in $whoopie. Not sure how to turn this one out. 🙁
Thanks!

Guess I needed a walk to think.
I did this:
$selection = ($$Make) ;
and then use the key names from the whoopie array as $selection[chains].

{$$Make}["chains"] should work too
