Hi Jason,

It sounds like you do not fully understand how PHP and HTML are
interacting in your code (the links at the bottom will help but maybe
my slightly wordy explanation will too).

The code you have been given: echo "<option value='$id'>$section</
option>\n";
Puts the ID in the value (not visible to the user) attribute of the
option tag (this is what gets
sent back to the server in the GET/POST array) the SECTION will be
displayed as the text within the
visible part of the drop down list. If for some reason you want to
concatenate the ID and Section
together you can just go:

echo "<option value=\"".$id.$section."\">".$section."</option>\n";

NOTE: I have used double quotes which makes a few extra escape
characters necessary, and I'm also using the . to concatenate the
various parts of the string. This is just a personal preference thing
and there are plenty of other valid ways you can achieve the same
result.
