Description:
------------
this is one of the lines in the fleets page (1329) which is throwing errors.

$pages = array($page1, $page2, $page3, $page4, $page5, $page6, $page7);

the variable $page1,....,$page7 are used by this line everytime the page is opened   and usually most of them are undefined (well page1 and 2 are almost always defined, but page 7 is almost never done.)

The error is a php issue complaining that several page variables are undefined. It only occurs some of the time, and i've no clue what is throwing it.


Reproduce code:
---------------
$pages = array($page1, $page2, $page3, $page4, $page5, $page6, $page7);

Expected result:
----------------
$page1 through $page7 to be properly defined. 

Actual result:
--------------
the variable $page1,....,$page7 are used by this line every time the page is opened   and usually most of them are undefined (well page1 and 2 are almost always defined, but page 7 is almost never done.)
