I am fairly stuck with the following code. I keep getting an error message
stating "sortField is null or is not an object" If anyone can help me
point out the problem with my code, it would be greatly appreciated. (the
code is shown below). This stylesheet is linked to an xml document with
the following format.
<current_projects xmlns="x-schema:sortProjects-schema.xml">
<contents>Project Listing</contents>
<date_span>2000 - 2001</date_span>
<project>
<project_title>PenMap Demonstration</project_title>
<project_number>6</project_number>
