Good spotting... I had read over those instructions but not well enough. So I went here - http://code.jquery.com/jquery-1.10.2.js - and saved the uncompressed version to my Shared Documents folder - is that right? Then changed my script to:-
<script language="javascript" type="text/javascript" src="/Shared%20Documents/jQuery-1.10.2.min.js"></script>
<script language="javascript" type="text/javascript" src="/Shared%20Documents/jquery.SPServices-2013.01.min.js"></script>
<script language="javascript" type="text/javascript">
$(document).ready(function() {
$().SPServices.SPCascadeDropdowns({
relationshipList: "Countries",
relationshipListParentColumn: "Continent",
relationshipListChildColumn: "Country",
parentColumn: "Continent",
childColumn: "Country"
debug: true
});
});
</script>
Still won't work :-(
