[PHP] Including function libraries

[Andrew W]

Ok, I've got a file called functions.lib which contains the following:
function checkLoggedIn()
{
        return (true);
}
function Test ($x)
{
        return ($x * $x);
}
and a file called test.php which contains the following:
<?php
include 'functions.lib';
if (checkLoggedIn())
{
        print "Logged in";
}
else
{
        print "Not logged in";
}

?>
They're both stored in a directory called 'test' which Ive uploaded to 
my webserver.  When I call test.php from my browser I get the following 
output:

 function checkLoggedIn() {  return (true); }  function Test ($x) {  
return ($x * $x); }
Fatal error: Call to undefined function: checkloggedin() in 
/home/sites/site116/web/test/test.php on line 5

Why can't I call the function defined in the lib file?
Thanks
