Passing var

Hi

I have this problem:
Lets say I have index.php
Inside index.php i have these lines of codes:

include_once (“breadcrumbs.inc”); // to include breadcrumbs
include_once (“main_template.inc”); // insert the main layout
$breadcrumbs = $detail; // which breadcrumb that I want to insert
$subject2 = “This should appear”;

Then inside breadcrumbs.inc i have these:
$detail="
<div><a href=“index.php”>Home</>a</div>
<div><a href=“myworksmotion.php”> " . $subject2 . "</a></div>
";

But when I test it, it wont show “This should appear” on the brecrumbs location.

Any idea?
