My code below seems logical however i don't know why the sorting doesn't work with the error "Variable or parameter 'sort' is undefined.'"?

Could anyone point my mistake? thanksjava code to pass parameter\[code\]String sort = "rating";transformer.setParameter("sort", sort); /It will control the sort in xsl\[/code\]xml file\[code\] <?xml version="1.0" ?><cd> <title>A Funk Odyssey</title> <artist>Jamiroquai</artist> <tracklist> <track id="1"> <title>Feels So Good</title> <time>4:38</time> <rating>2</rating> </track> <track id="2"> <title>Little L</title> <time>4:10</time> <rating>5</rating> </track> <track id="3"> <title>You Give Me Something</title> <time>5:02</time> <rating>3</rating> </track> <track id="4"> <title>Corner of the Earth</title> <time>3:57</time> <rating>1</rating> </track> </tracklist></cd>\[/code\]This is my xsl\[code\] <?xml version="1.0" encoding="UTF-8"?><xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"><xsl
