Plugin Issue

Hello,

I have created a custom plugin called “KathysTest”
The only thing in this php file is:
<?php
/*
Plugin Name: Kathy Test
Plugin URI: http://www.bserv.com
Description: Kathys Test.
Version: 1.0
Author: BNS
License: GPL2
*/
function KathyTest()
{
print (“Kathy Test!”);
}
?>

When I call this plugin in my page:
<?php
KathyTest();
?>
only the ?> shows up on the page.

However, I tried this same plugin in another version of wordpress on my friend’s site and it works perfectly.

What could be the problem?
