Why not give each set of servers a name? Surely they're grouped

Step back from the code and consider the steps you need to perform...
1) Get an array of the categories, ideally in the form $cats[]
= categoryname.
2) Get an array of the category IDs that should be selected, i.e.
$selectedcats = array(3, 5, 7, 9).
3) Start the HTML select element
4) foreach ($cats as $id => $catname)
5) Determine whether it should be selected. e.g. $selected =
(in_array($id, $selectedcats) ? 'selected="selected"' : ''.
6) Output the HTML option element, like $catname, escaping where appropriate.
7) End of loop, job done.
If your code doesn't have that structure then you may want to consider
starting again.
Secondly, check that you're not using the same variable name twice. In
one of your previous emails you used $selected to hold the array of
selected categories, and in another you used it for the text to be
inserted into the option element. The latter will blat over the former
leading to no more than 1 option selected, and even then only if it's
the first option displayed.
If you're still stuck please post more of your code in a single chunk
including all the elements in my step-by-step above. The snippets
you're currently posting are not giving us enough context to spot even
the most common mistakes.
And if anyone cares... the zoo was great!!

Can you post the HTML you're getting for this select using the above
code. If the selected attributes are in the code correctly then there
must be a syntax error in there somewhere and the easiest way to find
it will be by looking at the HTML.

If you use this method then you'll completely ignore a form submission

;Balance"]; " it works fine.
Well, duh! If you add periods and commas it will make it a text variable
and will no longer equate to 10000. You need to format it after the
comparisons.

That destroys the file but (at least the docs say) does not clean out
the global variables, and does not seem to work in

if (isset($_GET['guessnumb']))
{
