Error reporting will have not included notices on the previous server which is why you haven't seen the errors.
You should be checking whether the index s actually exists in the $_GET array before attempting to use it.
Something like this would be suffice:
if (isset($_GET['s'])) {
if ($_GET['s'] == 'jwshxnsyllabus')
echo "<body onload=\"loadSyllabi('syllabus', '../syllabi/jwshxnporsyllabus.xml', '../bibliographies/jwshxnbibliography_')\">";
else if ($_GET['s'] == 'aquinas')
echo "<body onload=\"loadSyllabi('syllabus', '../syllabi/AquinasSyllabus.xml')\">";
else if ($_GET['s'] == 'POP2')
echo "<body onload=\"loadSyllabi('POP2')\">";
} else {
echo "<body>";
}It may be beneficial (if you plan on adding more cases) to use a switch statement to make your code more readable.
switch ((isset($_GET['s']) ? $_GET['s'] : '')) {
case 'jwshxnsyllabus':
echo "<body onload=\"loadSyllabi('syllabus', '../syllabi/jwshxnporsyllabus.xml', '../bibliographies/jwshxnbibliography_')\">";
break;
case 'aquinas':
echo "<body onload=\"loadSyllabi('syllabus', '../syllabi/AquinasSyllabus.xml')\">";
break;
case 'POP2':
echo "<body onload=\"loadSyllabi('POP2')\">";
break;
default:
echo "<body>";
break;
}EDIT: BTW, the first set of code I wrote mimics what yours is meant to do in it's entirety. Is the expected outcome of an unexpected value in ?s= meant to output no <body> tag or was this an oversight? Note that the switch will fix this by always defaulting to <body>.

A new problem has arisen for me as I tried to run my script on a different PHP Server.
ON my old server the following code appears to work fine - even when no
sparameter is declared.But now, on a my local server on my local machine (XAMPP - Apache) I get the following error when no value for
sis defined.What I want to happen for the script to call certain javascript functions if a value is declared for
s, but if nothing is declared i would like the page to load normally.Can you help me?
